As to the problem of the digital fashion images suffered from the regular pattern clothes with fence which could generate some color ripple pattern in digital fashion images,the algorithm of moire cancellation for digital fashion images was researched.According to studying on the reason of moire ripple's generation and the Bayer CFA's arrangement,an algorithm which had two steps: moire ripple detection and moire cancellation.Firstly,the images' G channel was filtered with horizontal and vertical by high through filter which can simulate the alias.This step can detect the moire ripple in image.And then for G channel,the horizontal interpolation can be the basis of R and B channel's interpolation which can be constructed to the image without moire ripple.The experimental results demonstrated that this method has the superiority of saving the quantity of images compared with the method of reconstitution based on JPEG image which was proposed by Yoga.
