  • SYSTEMS AND METHODS FOR PROCESSING SHADOWS IN COMPRESSED VIDEO IMAGES
    Publication number: 20120275524
    Abstract: Methods and systems are disclosed for processing compressed video images. A processor detects a candidate object region from the compressed video images. The candidate object region includes a moving object and a shadow associated with the moving object. For each data block in the candidate object region, the processor calculates an amount of encoding data used to encode temporal changes in the respective data block. The processor then identifies the shadow in the candidate object region composed of data blocks each having the amount of encoding data below a threshold value.
