| Abstract: | This paper introduces the basic modes of image parallel processing, and analyzes the parallel processing ability and stream program mode of CPU. Then it brings forward a basic flow of SAM parallel algorithmic based on GPU, and discusses the key technical problems such as: data loading, computational result feedback and saving. At last, it makes a system experiment on TM images to prove the validity of this method. |
