Person localizing process for e.g. video telephone scenes filtering field, involves choosing active contour algorithm for video image to apply to initial contour for obtaining final contour localizing person to be extracted in image

摘要

The process involves performing an initial segmentation of a video image based on an average saturation of the image and its comparison to a preset threshold. A model is applied to the segmented image and an initial contour of the image is deducted. An active contour algorithm for the image is chosen and applied to the initial contour for obtaining a final contour localizing a person to be extracted in the image. An independent claim is also included for a computer program product having instructions for implementing a process of localizing a person in a video image.
