METHOD AND APPARATUS FOR SKIN COLOR CORRECTION AND DIGITAL PHOTOGRAPHING APPARATUS USING BOTH |
摘要 |
An apparatus and method of correcting skin color in an image is disclosed. The method may include extracting skin colors; analyzing the extracted skin colors to calculate axes of a different vector space; transforming the extracted skin colors to the different vector space; using the result of the transformed skin colors to identify a color from an input image as a skin color; and correcting the color identified as a skin color. The different vector space may be a principal components analysis (PCA) vector space. Extracting skin colors may include detecting a face region as a skin region in an input image and extracting skin colors from the face region. A lookup table be generated according to the result of projecting the skin colors to fewer dimensions of the different vector space. Extracting skin colors may include extracting colors from a training image of skin colors.
