Joint deconvolution for ultrasound imaging

Increasing axial resolution of ultrasonic imaging with a joint sparse representation model

This code uses a joint sparse representation model to increase axial resolution of ultrasonic imaging. The proposed model combines the sparse deconvolution along the axial direction with a sparsity-favoring constraint along the lateral direction. For detailed information, see J. Duan et al., "Increasing axial resolution of ultrasonic imaging with a joint sparse representation model".
