摘要
A method of extracting error for peak signal to noise ratio (PSNR) computation in an adaptive scalable texture compression (ASTC) encoder. The method includes identifying a pixel positions of a pixel in a coded block. The pixel position corresponds to an index in a decimated weight block. The method extracts an error value corresponding to the identified pixel position for said PSNR computation in said ASTC encoder.
