WebImage segmentation is a function that takes image inputs and produces an output. The output is a mask or a matrix with various elements specifying the object class or instance to which each pixel belongs. Several relevant heuristics, or high-level image features, can be useful for image segmentation. WebApr 14, 2024 · Unlike object detection, image classification puts an entire image (or video frame) through a machine learning classifier, such as a deep neural network. This process generates tags or labels, and then human annotators or AI-based automated labeling software must apply those labels to the correct object in the images.
