DeepLab

DeepLab is a deep learning model developed by Google for semantic image segmentation. It employs convolutional neural networks (CNNs) to classify each pixel in an image, enabling a detailed understanding of the scene. The architecture incorporates atrous convolution (dilated convolution) to enlarge the field of view of filters without increasing the number of parameters, allowing the model to capture long-range contextual information. Key components include Atrous Spatial Pyramid Pooling (ASPP) which probes the incoming convolutional feature layer with filters at multiple sampling rates and effective fields-of-view, thus capturing objects as well as image context at multiple scales. DeepLab models are open-sourced under the TensorFlow framework, facilitating use in a wide range of computer vision applications such as autonomous driving, medical imaging, and augmented reality.
