In this paper, an adaptive error concealment method is proposed to recover the motion vectors of degraded macroblocks (MBs) in a frame, based on analyzing the behavior of the MBs in the frames. In this method, the behavior of the degraded MB is first estimated considering the obtained information from motion vectors of neighboring MBs in the current frame and collocated MBs in the previous frames...
Edge detection is one of the most commonly used operations in image analysis and machine vision. This means that if the edges in an image can be identified accurately and localized properly, all of the objects and elements can be located and basic properties such as area, perimeter, and shape can be measured. One new trend in edge detection starts from knowledge about the Human Visual System (HVS)...
The classification of the sound heart into different valve-physiological heart disease categories is a complex pattern recognition task. This paper will purpose sound heart recognition for diagnosing heart disease with 4 type of Artificial Neural Network (ANN). We develop a simple model for the recognition of heart sounds, and demonstrate its utility in identifying features useful in diagnosis. We...
