Abstract
A method of processing video data (300) is disclosed. The video data (300) comprises a plurality of sets of frame data and is captured by mobile video data capture means. The method comprises: (a) finding a face in each frame of the video (400); and (b) processing a corresponding set of frame data to: (i) maintain the area of the image occupied by the face substantially constant (400); and (ii) maintain the apparent direction of light incident upon the face substantially constant (500); and/or (iii) maintain the apparent colour of the face substantially constant (600).
Claims15
A method of processing video data captured by mobile video data capture means, said video data comprising a plurality of sets of frame data, said method comprising:
- (a) finding a face in each frame of said video;
- and
- (b) processing a corresponding set of frame data to:
- (i) maintain the area of the image occupied by said face substantially constant;
- and
- (ii) maintain the apparent direction of light incident upon said face substantially constant;
- and/or
- (iii) maintain the apparent colour of said face substantially constant.
Video processing means including:
- a storage medium having recorded therein processor readable code processable to process video data captured by mobile video data capture means, said video data comprising a plurality of sets of frame data, said code comprising:
- identification code processable to identify a face in each frame of said video;
- and
- frame data processing code processable to process a corresponding set of frame data to:
- (i) maintain the area of the image occupied by said face substantially constant;
- and
- (II) maintain the apparent direction of light incident upon said face substantially constant;
- and/or
- (iii) maintain the apparent colour of said face substantially constant.
A portable device comprising:
- video data capture means, said video data comprising a plurality of sets of frame data;
- a storage medium having recorded therein processor readable code processable to process said captured video data, said code comprising:
- identification code processable to identify a face in each frame of said video;
- and
- frame data processing code processable to process a corresponding set of frame data to:
- (i) maintain the area of the image occupied by said face substantially constant;
- and
- (ii) maintain the apparent direction of light incident upon said face substantially constant;
- and/or
- (iii) maintain the apparent colour of said face substantially constant.
