Algorithm 1

The flow of linear image recovering.

Task: Linearly recovering each image block , .

Input:   CSmeasurement vectors , , and block measurement matrices , .

Step:

    (a) Compute the auto-correlation matrix according to Eq. (13);

    (b) Compute the projection matrix according to Eq. (11);

    (c) Reconstruct each image block , according to Eq. (15);

    (d) Merge all image block into a whole image .

Output: The recovered image .
