In order to calculate number of pixel in the segmented area, i need to remove the class labels and the predictions percentage in the picture. Returns: predictions (dict): the output of the model. This often involves filtering detections from the model. Now I'm trying to use the prediction boxes to crop the image (in my use case there is only 1 object/box detected per image). It is a framework for image segmentation and object detection. For instance, you may want to retrieve detections from a model that are above a specified confidence level, or detections in a particular region of an image or video. join (cfg. Before a model goes to production, you need to build logic around the model. The pipeline will run You signed in with another tab or window. Modified 3 years, 1 month ago. path.
