Real-time face detection using pixel pairs

摘要

The subject disclosure is directed towards a face detection technology in which image data is classified as being a non-face image or a face image. Image data is processed into an image pyramid. Features, comprising pixel pairs of the image pyramid, are provided to stages of a cascading classifier to remove sub-window candidates that are classified as non-face sub-windows within each stage. The face detection technology continues with one or more subsequent stages to output a result as to whether the image contains a face.

主权项

1. In a computing environment, a method comprising:
processing image data into an image pyramid; providing features of sub-window candidates to each stage of a cascading classifier to remove zero or more sub-window candidates that are classified as non-face sub-windows within that stage, in which the features comprise pixel pairs of the image pyramid; continuing with one or more subsequent stages; and outputting a result based upon whether at least one sub-window candidate remains.
