I work on image compression at compressed sensing field and i need to use image as an application. I use DWT for image and convert it to sparse signal.How can i recover sparse signal as an image with DWT?

As the first step of decoding, multiply with the inverse of orthonormal random matrix with the received compressed image. You need to take the help of optimization techniques. Try using L1 minimization. L1 magic is its toolbox. I am currently doing the work in the same project. Its just not complete yet. After optimization take the inverse dwt and you get the orginal image.
