In this paper, we propose a fast Motion Estimation (ME) algorithm with Adaptive Search Range (ASR) decision to further accelerate the Graphics Processing Units (GPU)-based ME for High Efficiency Video Coding (HEVC). The proposed approach adaptively decides search ranges on the Central Processing Unit (CPU) and transfers them to the GPU. Then, the GPU(More)
Epigenetic modifications affect gene expression and thereby govern a wide range of biological processes such as differentiation, development and tumorigenesis. Recent initiatives to define genome-wide DNA methylation and histone modification profiles by microarray and sequencing methods have led to the construction of databases. These databases are(More)
The environment of transmission via a wireless network is not always error-free. The loss of data or impairment caused by errors degrades the quality of image. The error concealment is the method that finds the best substitute information from the previous reference image with the boundary information around lost block. Therefore, This paper proposes an(More)
On the channel of wireless transmission environment, there is the data loss suffered from a packet loss. A packet loss brings lowering of image quality of the decoded image. Error concealment method is the efficient method that reduces lowering of performance in having error. This study introduces a method of Adaptive MultiSide Boundary Matching(More)
