In addition, many of the features that define the OS X user experience—such as Notification Center, full-screen mode, and Auto Save—are implemented by the Cocoa layer. The term Aqua refers to the overall appearance and behavior of OS X. The Aqua look and feel is characterized by consistent, user-friendly behaviors combined with a masterful use of layout, color, and texture.
Although much of the Aqua look and feel comes for free when you use Cocoa technologies to develop your app, there are still many steps you should take to distinguish your app from the competition. To create a beautiful, compelling app that users will love, be sure to follow the guidance provided in OS X Human Interface Guidelines.
The Cocoa Application layer implements many features that are distinctive aspects of the OS X user experience. Notification Center provides a way for users to receive and view app notifications in an attractive, unobtrusive way. The Notification Center APIs, which help you configure the user-visible portions of a notification item, schedule items for delivery, and find out when items have been delivered.
You can also determine whether your app has launched as a result of a notification, and if it has, whether that notification is a local or remote that is, push notification. To ensure that your app gives users the best Notification Center experience, read Notification Center. Game Center accesses the same social-gaming network as on iOS, allowing users to track scores on a leaderboard, compare their in-game achievements, invite friends to play a game, and start a multiplayer game through automatic matching.
Game Center functionality is provided in three parts:. The Game Center app, in which users sign in to their account, discover new games and new friends, add friends to their gaming network, and browse leaderboards and achievements. The Game Kit framework, which contains the APIs developers use to support live multiplayer or turn-based games and adopt other Game Center features, such as in-game voice chat and leaderboard access.
The online Game Center service supported by Apple, which performs player authentication, provides leaderboard and achievement information, and handles invitations and automatching for multiplayer games.
In your game, use the Game Kit APIs to post scores and achievements to the Game Center service and to display leaderboards in your user interface. The sharing service provides a consistent user experience for sharing content among many types of services.
For example, a user might want to share a photo by posting it in a Twitter message, attaching it to an email, or sending it to another Mac user via AirDrop. As a result, you can display a custom UI to present the services.
You can also use the NSSharingServicePicker class to display a list of sharing services including custom services that you define from which the user can choose. When a service is performed, the system-provided sharing window is displayed, where the user can comment or add recipients. Resume is a systemwide enhancement of the user experience that supports app persistence. A user can log out or shut down the operating system, and on next login or startup, OS X automatically relaunches the apps that were last running and restores the windows that were last opened.
If your app provides the necessary support, reopened windows have the same size and location as before; in addition, window contents are scrolled to the previous position and selections are restored. To support app persistence, you must also implement automatic and sudden app termination, user interface preservation, and Auto Save. When an app enters full-screen mode it opens its frontmost app or document window in a separate space.
Enabling full-screen mode adds an Enter Full Screen menu item to the View menu or, if there is no View menu, to the Window menu. When a user chooses this menu item, the frontmost app or document window fills the entire screen.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

COCO is a large image dataset designed for object detection, segmentation, person keypoints detection, stuff segmentation, and caption generation. The exact format of the annotations is also described on the COCO website.
Both are available on the project website. To support Windows build and python3 we had to make minor changes to:. If you don't, make sure to install them from here :. It happens because there is a pycocotools directory in the same folder as the notebooks.
The python code being imported then is the local implementation of pycocotoolsnot the one installed with pip. To fix this issue, the demo notebooks have been moved to their own directory. Instead, you are inadvertently referencing a local copy of the library. So, if you get this error, search the tree of import in your code for a reference to a local pycocotools library. Then, move or delete the local version. We use optional third-party analytics cookies to understand how you use GitHub.

Instead of the official version which has issues with python 3 use an alternative one. Install it on your local machine, globally i. You can do this by:. Now, inside your virtual-env conda or whateverfirst install numpy and cython and maybe setuptools if it's not installed using pipand then:. Inside your project, import for example from pycocotools import mask as mask and then print mask.
This should print out the author's name, which is tsungyi. The installed package, like any other packages that are locally installed inside a virtual-env using pipwill go to External Libraries of your project, under site-packages. That means it is now part of your virtual-env and not part of your project. So, other users who may want to use your code, must repeat this installation on their virtual-env as well. The main source of confusion is that either you did not install the required packages before installing cocoapi, or you did install the required packages but for a different python version.
And when you want to check if something is installed, you may check with, for instance, python 3. So suppose you are using python3. You need to make sure that:. If this is not the case, you can change your default python using sudo update-alternatives --config pythonand following the one-step instruction. All the required packages are installed using the right python or pip version. To install the required packages, after you made sure about 1you need to run: sudo apt install python-setuptools python3.
Environment: The above steps were tested on Ubuntu There are alternative versions of the cocoapi that you can download and use too I'm using python 3. Here's a solution that you might want to try out: How to download and use object detection datasets e.

Aug 2, Jun 12, Feb 20, Sep 6, May 3, Oct 16, This class manages 3D reconstruction by fusing raw accelerometer, gyro, color camera, and TrueDepth camera data in real time.
Now that your color and depth data is coming in, you may want to visualize these single frames in 3D. To do that, reconstruct a single depth frame into a point cloud by calling reconstructSingleDepthBufferthen render the resulting SCPointCloud to your liking.
The SCReconstructionManager will call the following delegate method with every incremental assimilated frame. When the user finishes scanning, stop passing in this data and call finalizewhich does some post-processing cleanup and returns the final, reconstructed point cloud.
The point cloud wraps a single, interleaved buffer of point positions, colors, normals, and more. To visualize the reconstructed point cloud, you may use the SceneKit helper methods to build an SCNNode representing this point cloud, or the Metal helper methods to render it yourself.
You may tweak any of these parameters, but the default values are great for the vast majority of scanning applications. Contains a reconstructed point cloud, both during and at the end of a scanning session. The points are represented as a packed array of points, wrapped in an NSData. Each point has a position, normal, RGB color, and other attributes, e. This does not represent a mesh, as StandardCyborgFusion does not yet create meshes directly from scanning. Though you can use SCMeshingOperation to mesh scans.
Helpful components for iOS apps to use for driving the StandardCyborgFusion framework and visualizing scanning and results. It is not necessary to use these classes in an app that already has a video pipeline and rendering, but many apps may find these classes helpful to use.
You can use these classes independently of each other. Shows a live depth preview with a shutter and a cancel button, and manages scanning sessions. Owns a CameraManager. Owns a default ScanningViewRendererwhich may be set to another conforming object to customize rendering. Renders an interactive preview of an SCPointCloud.
Provides two buttons which may be customized to perform your own actions. Instantiate this view controller with an SCPointCloud instance and present it. You may customize the buttons by direclty mutating its leftButton and rightButton. Also requests camera access and manages camera state in response to appplication state transitions and interruptions. ScanningViewController already owns an instance of this, but it might be useful to use a CameraManager if building your own custom scanning view controller.
It is recommended to use an instance of CameraManager from within a view controller, like this:. To use your own rendering in a ScanningViewControllerimplement a class or struct conforming to this protocol. Then, set ScanningViewController. Cocoa API Documentation. SCReconstructionManager Overview This class manages 3D reconstruction by fusing raw accelerometer, gyro, color camera, and TrueDepth camera data in real time. Start streaming CMDeviceMotion data.Cocoa is Apple 's native object-oriented application programming interface API for its desktop operating system macOS.
Cocoa applications are typically developed using the development tools provided by Apple, specifically Xcode formerly Project Builder and Interface Builder now part of Xcodeusing the programming languages Objective-C or Swift.
A Ruby language implementation named MacRubywhich removes the need for a bridge mechanism, was formerly developed by Apple, while Nu is a Lisp -like language that can be used with Cocoa with no bridge. For end-usersCocoa applications are those written using the Cocoa programming environment. Such applications usually have a familiar look and feel, since the Cocoa programming environment automates many aspects of an application to comply with Apple's human interface guidelines.The Hard Aches - I Get Like This
Apple acquired NeXT in Decemberand subsequently went to work on the Rhapsody operating system that was to be the direct successor of OpenStep. The OpenStep base of libraries and binary support was termed Yellow Box. However, differences exist. The resulting software framework received the name Cocoa for the sake of expediency, because the name had already been trademarked by Apple. For many years before this present use of the name, Apple's Cocoa trademark had originated as the name of a multimedia project design application for children.
The application was originally developed at the Apple Advanced Technology Group under the name KidSimand was then renamed and trademarked as "Cocoa". The name, coined by Peter Jensen who was hired to develop Cocoa for Apple, was intended to evoke "Java for kids", as it ran embedded in web pages. The original "Cocoa" program was discontinued at Apple in one of the rationalizations that followed Steve Jobs 's return to Apple.
It was then licensed to a third party and marketed as Stagecast Creator as of [update]. One feature of the Cocoa environment is its facility for managing dynamically allocated memory. Foundation Kit 's NSObject class, from which most classes, both vendor and user, are derived, implements a reference counting scheme for memory management.
Objects that derive from the NSObject root class respond to a retain and a release message, and keep a retain count. A method titled retainCount exists, but contrary to its name, will usually not return the exact retain count of an object. It is mainly used for system-level purposes. Invoking it manually is not recommended by Apple. A newly allocated object created with alloc or copy has a retain count of one.
Sending that object a retain message increments the retain count, while sending it a release message decrements the retain count. Starting with Objective-C 2.
Mac Technology Overview
In this model, the runtime turned Cocoa reference counting operations such as "retain" and "release" into no-ops. The garbage collector does not exist on the iOS implementation of Objective-C 2.
Garbage collection in Objective-C ran on a low-priority background thread, and can halt on Cocoa's user events, with the intention of keeping the user experience responsive. The legacy garbage collector is still available on Mac OS X version Inthe LLVM compiler introduced Automatic Reference Counting ARCwhich replaces the conventional garbage collector by performing static analysis of Objective-C source code and inserting retain and release messages as necessary.
Cocoa consists of three Objective-C object libraries called frameworks.
