Face detection based on a new color space YCgCr
Juan Jose de Dios, Narciso N. Garcia · 2004
A new color space, YCgCr, is described and applied for face detection. Although similar to the YCbCr color space, it differs in the use of the Cg color component instead of the Cb one. Here, the fundamentals of this new color space YCgCr are presented and its capabilities and advantages over YCbCr are analyzed. After describing the face extraction technique and the required decision values, the parameters which determine the decision thresholds are modeled and represented in the Cg-Cr plane. Based on the representation of the experimental results, the decision thresholds are modified. Finally, the segmentations results achieved with this new color space are compared with those obtained in YCbCr.
