カラー画像のアダマール変換符号化と画像圧縮

概要

論文の詳細を見る
Image compression and coding techniques basically involve the processing of images prior to transmission. Measures of the above algorithm performance are composed of three entities : (a)amount of data reduction. (b) quantitative or qualitative assessment of the degradation of the image data, and (c) compression/expansion processing speed. In this study, a set of RGB components of color images is transformed into a set of YIQ data. Hadamard transform coding of the Y component of color images is performed. The features of a boundary threshold method in contrast to other some methods are discussed together with the quantitative measure such as the degree of similarity and the ratio of file compression. Reconstructed images after executing compression and expansion are presented in order to demonstrate a visual assessment of the degradation of the images.
