H.264 coding technology is the most commonly-used video compression technology. As H.264 videos in transmission, video packet losses inevitably occur. The error concealment method can solve the problem. For the lost block, we use the motion vector of neighboring available block to estimate the lost motion vectors, and the estimates propagate to predict all(More)
This paper investigates the resource management problem in the relay-enhanced long term evolution advanced (LTE-A) systems. The challenges of this resource allocation problem arise from the complication of assigning transmission links to the multicast broadcast single frequency network (MBSFN) subframe within the numerous physical resource block (PRB) pair.(More)
Sparsity analysis of images is important to understand the image characteristic and its possible potential in applications. In this paper, normal images and endoscopy image are investigated for their sparsity using K-SVD algorithm that finds a dictionary basis with minimal number of non-zero coefficients in the transformed domain to have minimal prediction(More)
