Description

technical field [0001] The invention relates to the fields of pattern recognition and computer vision, in particular to a semantic segmentation method in a BiSeNet-based automatic driving scene. Background technique [0002] Semantic image segmentation is an essential part of modern autonomous driving systems, as an accurate understanding of the scene around the car is critical for navigation and action planning. Semantic segmentation can help autonomous vehicles identify drivable areas in an image. Since the emergence of Fully Convolutional Networks (FCN, Fully Convolutional Networks), convolutional neural networks have gradually become the mainstream method for processing semantic segmentation tasks, many of which are directly borrowed from convolutional neural network methods in other fields. In the past ten years, many scholars have made great efforts in the creation of semantic segmentation datasets and algorithm improvement. Thanks to the development of deep learning...
