Image fusion is a very important step for image mosaic. Fusion algorithms affect the visual effect and quality of the mosaic images directly. This paper presents an adaptive weighted coefficients algorithm for image fusion. The algorithm can adjust weighted coefficients adaptively along with changes of the range and shape of the overlapping regions. First, Harris operator is used to detect feature...
SELinux is a strong and flexible system with a well-defined MAC architecture. It provides a mechanism to enforce the access control based on confidentiality and integrity requirements which offers an effective protection of information security. This paper describes in what way SELinux uses various models and policies to secure the information safety which different from others, especially from a...
In this paper, we propose a novel fast mode decision scheme for intra-frame and inter-frame in the H.264/AVC video coding standard. This algorithm only computes the best likely modes which are selected by the value of variance (second moment). The variance is used to measure the smoothness and coarseness of the texture, and then a few modes are selected according to the value of variance. The proposed...
