APPARATUS AND METHOD FOR COLOR CALIBRATION

摘要

The present invention relates to an apparatus and a method for mapping the colors of at least one source image to the colors of a reference image. The apparatus comprises a histogram matching unit (52) adapted to match the histogram of the source image to the histogram of the reference image so as to generate a histogram matched image of the source image, a probability distribution computation unit (54) adapted to generate a conditional probability distribution of the reference image, and an outlier detection unit (55) adapted to detect outliers in the histogram matched image on the basis of the conditional probability distribution.
