| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | An application of information hiding to image compression is investigated to improve compression efficiency for JPEG color images, where entropy coded DCT coefficients of chrominance components are embedded into DCT coefficients of luminance components. In the proposed method, a color image is changed to a JPEG monochrome image with only luminance components. A color image can be recovered from the monochrome image by extracting chrominance components. To recover an image from degradation caused by compression and embedding, an image restoration method based on the MAP estimation is also applied. Experimental results show that information hiding improves compression efficiency to some extent and image restoration improves it more than information hiding. | |
