Abstract: A modified color transfer method based on Welsh's algorithm is introduced to raise the color transfer speed and accuracy,and improve the effects between dissimilar images.Firstly,RGB signals are converted to visual perception-based color space lαβ,and feature vector is formed by the mean values and standard deviation according to a certain standard.Local vector of swatches between the target and the source image are matched and calculated according to the principle that the corresponding local areas have similar characteristics.The experimental results demonstrate that the proposed algorithm is of high computation precision,fast transfer speed and strong disturbance rejection between dissimilar images.
