So we use the do / catch block where if there is any error thrown by the perform() method it is caught in the catch block and handled appropriately. The handler.perform() definition reveals that it can throw an error: open func perform ( _ requests: ) throws Take a look at the do, try & catch syntax in the above code. In our case we only one have one so we will just pass that. perform() method to pass in an array of Vision request. Once the handler is created we are using the. This VNImageRequestHandler will handle our Vision request. We are using the URL and options constructor to create an instance of this handler.

In the a new function called predict(url: URL) which takes in a URL, we are creating an VNImageRequestHandler. Let handler = VNImageRequestHandler(url: url, options: ) Let segmentedDrawingView: DrawingSegmentationView = Img.translatesAutoresizingMaskIntoConstraints = false Img.image = UIImage(systemName: 'hare.fill') We will have an UIImageView placed in the center of the view with a button underneath it and a UIBarButtonItem on the top right side of the navigation bar. In the ViewController, make sure to import Vision. Let's begin by first heading over to this site and downloading the DeepLabV3 model. In this tutorial we will use Apple's Vision framework along with CoreML DeepLabV3 model to do image classification and segmentation and make the background of an image black while maintaining the color of the subject in the foreground. There are numerous applications for image segmentation. You may want to do image segmentation when trying to add a black and white background while maintaining the color of the foreground. Image Segmentation is a way to divide an image into multiple segments depending upon the subject. In this tutorial, we will using the Vision and CoreML frameworks to make an Image Segmentation app.
