An improved scheme for transmission of panoramic images with regions of interest

In order to realize the effective and speedy transmission for panoramic images with region of interest (ROI),we used LDPC- based channel coding method to transmit the images in consideration of the characteristics of panorama image. The ROI was protected with unequal error protection strategy, that is, for ROI the LDPC code with long code length and low code rate was employed; whereas for non ROI, LDPC code with short code length and high code rate was adopted. Therefore, the quality of ROI of image is obviously better than that of background while the transmission quality of the whole image is guaranteed.
