Semantic segmentation is another critical task in computer vision, aiming to label each pixel in an image with a corresponding class. This task is essential for tasks such as autonomous driving and medical image analysis. The main challenge in semantic segmentation is to achieve high accuracy while maintaining a reasonable computational cost. Recent research in semantic segmentation has seen the development of various deep learning models, such as fully convolutional networks (FCNs) and encoder-decoder architectures, which have significantly improved the performance of semantic segmentation models.
4、3D Vision
3D vision is a branch of computer vision that focuses on understanding and interpreting the three-dimensional structure of the world. This task is crucial for applications such as augmented reality, robotics, and autonomous navigation. Recent research in 3D vision has focused on developing methods for estimating depth information from images, as well as reconstructing 3D models from a single image or a sequence of images.
