Abstract:
Flesh-tones corrections may be performed to correct color shifts that may occur in transmitted video frames wherein chroma information corresponding to flesh-tone video pixels may be distorted. A target region may be determined based on a determined flesh-tones region within a spatial representation of chroma in video color space, such as Y′CrCb. The flesh-tones correction may utilize one or more methodologies based on an elliptical shape and/or a triangular shape algorithm(s). A video processing system may be utilized to analyze chroma information of received video pixels and/or to perform flesh-tones corrections by shifting the chroma value of received video pixels towards good flesh-tones regions to compensate for possible distortions. The video processing system may perform conversion calculation and/or shift operations dynamically. The video processing system may also utilize lookup tables (LUTs) to convert received chroma values. The LUTs may be programmable to enable modifying and/or updating of the system.
