Embodiment 1
[0046] figure 1 It is a flow chart of a face detection method based on compressed information in a preferred embodiment of the present invention; the method includes:
[0047] Step1: According to the frame category of the current frame, set the face detection processing mode of the current frame.
[0048] If the current frame is an intra-frame prediction frame, then set the face detection processing mode of the current frame as an intra-frame processing mode; if not, set the face detection processing mode of the current frame as an inter-frame processing mode.
[0049] Step2: According to the face detection processing mode of the current frame, the face detection of the current frame is performed.
[0050] Step3: Enter the face detection of subsequent frames.
[0051] Determine whether the next frame of the current frame exists, if the next frame of the current frame is set as the current frame, return to Step1; if not, end.

Embodiment 2
[0085] Figure 5 It is a structural diagram of a face detection system based on compressed information in a preferred embodiment of the present invention. The system includes:
[0086] The face detection processing mode setting module includes a setting module, an intra-frame processing module, and an inter-frame processing module; the setting module is used to set the current frame face detection processing mode according to the frame category of the current frame; if the current frame is an intra-frame prediction frame, set to enter the intra-frame processing module; if not, set to enter the inter-frame processing module.
[0087] The first face detection module is configured to detect the face of the current frame according to the face detection processing mode of the current frame.
[0088] The next frame setting module is used for face detection in subsequent frames.
[0089] That is to judge whether the next frame of the current frame exists, if the next frame of the ...
