Embodiment Construction
[0033] An implementation example of the present invention is described in detail as follows in conjunction with accompanying drawing:
[0034] The H.264 compressed domain real-time video object segmentation method based on the motion feature of the present invention is according to the program block diagram shown in Figure 1, and the CPU is a dual-core 2.0GHz, internal memory 900M PC test platform programming implementation, Figure 4 and Figure 5 provide Simulation test results.
[0035] Referring to Fig. 1, the H.264 compressed domain real-time video object segmentation method based on the motion feature of the present invention first carries out spatial normalization to the motion vector field, then carries out weighted median filtering to the normalized motion vector field, and then based on motion The magnitude, divergence and curl of the three motion features of the vector field are divided into multiple objects according to the similarity of the motion features by using ...
