Compressive Sensing for the LENA Image

In this program, we will implement compressive sensing for the LENA image. The program author is Wei Sha, a professor in the Department of Electrical and Electronic Engineering at The University of Hong Kong. His email address is wsha@eee.hku.hk. We will employ advanced compressive sensing techniques to achieve this objective. These techniques enable more efficient image processing, reduce the storage space required for image data, and facilitate faster data transmission during transfer processes. This is a significant project as it contributes to improving image processing efficiency and minimizing storage requirements.

From a code implementation perspective, the program likely involves key components such as sparse representation of the LENA image using transforms like DCT or wavelets, measurement matrix generation (e.g., random Gaussian matrices), and reconstruction algorithms such as basis pursuit or orthogonal matching pursuit. The implementation would focus on optimizing the trade-off between compression ratio and reconstruction quality while maintaining computational efficiency.
