We designed two research tracks for developing new very low complexity image coding by using colorization method and compressive sampling. 1) New colorization based coding scheme without sending the positions of color information is studied. The positions can be estimated by grayscale image at the decoder side and local decoding allows us to obtain which position will be estimated. 2 It is well known that the texture component of natural image is difficult to compress. Our research reveals that, by utilizing the prior information about texture component, we can decode the texture component precisely from the noiselet coefficient. From these results, we successfully developed the component technologies for establishing the very low complexity image coding.

为了开发新的极低复杂度图像编码，我们设计了两条研究轨道，分别使用彩色化方法和压缩采样。1)研究了一种新的不需要发送颜色信息的彩色编码方案。在解码端可以通过灰度图像来估计位置，而局部解码可以得到要估计的位置。2众所周知，自然图像的纹理分量很难压缩。我们的研究表明，利用纹理分量的先验信息，我们可以从噪声小波系数中精确地解码纹理分量。根据这些结果，我们成功地开发了用于建立极低复杂度图像编码的组件技术。
