本研究主要是針對色彩影像進行影像的視覺強化,而主要以Retinex演算法為主。但因為影像經過Retinex處理過後,會使影像過度的強化,因此我們利用四分位S曲線再對光源影像做調整,使影像不致於過度的被強化,以符合人眼能接受的影像品質且提升影像的視覺品質。
An image enhancement in respect of the color features based on the Retinex with tone curve mapping is proposed. The tone curve is generated by a Quartile Sigmoid Function allowing the intensity adjustment be satisfied within the saturation level. Then the color component is then reconstructed to achieve the visual pleasant quality.
