摘要： A method for identifying a region of interest within an image includes receiving an image. The image is divided into a plurality of tiles. It is determined which of the plurality of tiles includes the region of interest. A graphics processing unit (GPU) calculates a pixel intensity histogram for tiles that have been determined to include the region of interest. The region of interest is identified based on the calculated pixel intensity histograms.
