Embodiment Construction
[0011] The specific implementation of the present invention will be described in detail below in conjunction with the flowchart and specific conditions.
[0012] In the specific implementation of the present invention, an energy-saving compressed sensing image coding method comprises the following steps:
[0013] (1), input image, carry out block segmentation to input image, be divided into several non-overlapping image blocks, method is:
[0014] Use the CMOS sensor array to obtain the image x of natural landscape perception, and input the image x of natural landscape perception into the encoder by the CMOS sensor array, divide the image into several non-overlapping image blocks, input the image x, Dimensions N=I r ×I c , divide x into blocks, the block size is B×B, and the image blocks are sorted from top to bottom and from left to right. Each image block is drawn into a column vector by raster scanning, and the i-th image block is represented as x i , i=1,2,...,n,n=N / B ...
