Deep Learning Based 3D Segmentation: A Survey
3D segmentation is a fundamental and challenging problem in computer vision with applications in autonomous driving, robotics, augmented reality and medical image analysis. It has received significant attention from the computer vision, graphics and machine learning communities. Conventional methods for 3D segmentation, based on hand-crafted features and machine learning classifiers, lack generalization ability. Driven by their success in 2D computer vision, deep learning techniques have recently become the tool of choice for 3D segmentation tasks. This has led to an influx of a large number of methods in the literature that have been evaluated on different benchmark datasets. Whereas survey papers on RGB-D and point cloud segmentation exist, there is a lack of an in-depth and recent survey that covers all 3D data modalities and application domains. This paper fills the gap and provides a comprehensive survey of the recent progress made in deep learning based 3D segmentation. It covers over 180 works, analyzes their strengths and limitations and discusses their competitive results on benchmark datasets. The survey provides a summary of the most commonly used pipelines and finally highlights promising research directions for the future.
