Quality Measure of Color Image Based on Three Dimensional Matrix Transform
基于3维矩阵变换的彩色图像质量评价方法研究

In this paper,DSF(definition,error sensitivity and objective fidelity),a new technique of color image quality measure has been proposed in which color image quality can be measured synthetically by calculating the objective fidelity,vision distortion and definition of a color image.The objective fidelity is a base for transverse comparison.While the vision distortion and definition is utilized for vertical evaluation.The great similarity among three frames of one image is taken into account fully and 3D-WDCT(three dimensional wide DCT) is used when the definition was calculated.Three frames,R,G and B,are integrated into one single mathematics model to be transformed.Against PSNR,this method will provide a better performance consistent with human visual characteristic.
