Flesh Tone Correction Algorithm for TV receivers [articol]

Abstract

In this paper, we propose a Flesh Tone Colour Correction Algorithm for broadcast video receivers. Flesh tone regions are a critical processing topic since skin tones are generally the most common to reference. The flesh tone correction region is extracted from the digital colour-difference signals (B-Y, R-Y) and adjusted for optimal flesh tone display. The correction is applied as colour variation, hence the processing is less intrusive than a full range correction approach and also
