Abstract

Based on observations that the visual quality has strong correlation with image gradients, gradient based image SoftCast (G-Cast) advocates to convey visual information by delivering image gradients. In G-Cast, both horizontal gradients and vertical gradients needs to be transmitted, even if the channel bandwidth is insufficient. This paper propose to send out the random projection measurements of the gradients instead of delivering gradients directly, so that the number of transmitted data can be adjusted according to bandwidth conditions. Experimental results validate the effectiveness of the the proposed transmission scheme under various channel signal-To-noise ratio (CSNR) and bandwidth conditions.
