As the state-of-the-art of the modern video compression standard, H.264 shows a high coding performance. Introducing the motion estimation method, it has ten times computation comparing to MPEG2. The high computational requirement makes it hard to implement on portable devices. According to the human visual system (HVS) research, human eyes can only focus on one area in a frame, which is called region-of-interest...
Image inpainting is an old technique to reconstitute the damaged artwork. Given a user-defined region, Digital image inpainting approaches can restore the damaged region automatically on digital images. In the inpainting algorithm this paper proposed, gradients of half-points in the neighborhood of a damaged point and its matching point are used to estimate the gray value of the damaged point, instead...
Since H.264 is a high performance coding standard in with high computational requirements, it is hard to implement on portable devices. According to the human visual system (HVS) research, human eyes can only focus on one area in a frame, which is called region-of-interest (ROI). This phenomenon gives a chance to code all macroblocks unequally. In this work, the ROI is detected using texture contrast...
