Other AbstractThe invention relates to a multiscale compressed sensing progressive coding method of an ROI. The method comprises the steps that ROI detection is carried out on an original image; WBCT decomposition is carried out a detected ROI, a transitional zone and a background, multiscale compressed sensing measurement is carried out on the detected ROI, the transitional zone and the background, and ROI advance coding is carried out on the measured values; and if the ROI is not discovered, WBCT decomposition and multiscale compressed sensing measurement are carried out on the original image, and progressive coding is then carried out. According to the method, the image is compressed in the multiscale compressed sensing technology, so that progressive coding of the image is realized; the method is excellent in anti-interference performance due to compressed sensing measurement; and compared with compressed sensing, multiscale compressed sensing can maintain more information including image texture and edges under the same compression ratio.
