摘要： Aspects disclosed herein generally related to a method and system for efficient blind source separation using a topological approach. The method and system comprise locating and separating the audio streams by constructing and simplifying contour tree in a built time-frequency smooth weighted histogram in the subsystems included. Thus, in one example, the audio streams can be separated and reproduced in a faster, more reliability, higher quality and more robust way.

摘要： The present invention is directed to a surround view system and method thereof. The surround view system comprises a surround image sensing module which obtains images of surrounding view and output image data, a vehicle status retrieval module which retrieves vehicle status information, a processing module which generates adaptive surround view based on the image data and the vehicle status information; and an outputting module which outputs the adaptive surround view.
