Abstract

Compressed video sequences generated using a (e.g., DCT) transform are partially decoded (202) to recover (204) the low-frequency transform coefficients (e.g., only the DC coefficients) from the encoded bitstream. The low-frequency coefficients are then used to generate blocks of image data that are subjected to motion-compensated inter-frame addition (206) to generate partially decoded images that can be used for subsequent processing, such as histogram analysis (208) for video parsing. The present invention avoids having to perform the computationally expensive inverse transform operations, while still achieving satisfactory results.
