In H.264/AVC, the discrete cosine transformation (DCT) coefficients of a residual block are often quantized to zeros. Such block is called a all-zero block(AZB). If such AZB can be detected before transformation, the computation of following transformation and quantization can be avoided. This will lead to significant saving both in encoding time. An efficient and simple AZBs detecting algorithm in...
In H.264/AVC, it is a common phenomenon that the transformation coefficients of a block are quantized to zero. Such block is called a all-zero block(AZB). in the process of mode decision, if a AZB can be detected early, the overhead of following transformation and quantization can be avoided. This will lead magnificent saving in encoding time. A fast mode decision algorithm based on AZBs detection...
Simulating a leaf’s shape is one of the most important modeling methods for plant modeling and visualization. In this paper, a modeling method is presented which is based on the morphological characteristics of leaves. According to these characteristics, the geometric feature points are selected in the leaves’ edge outlines firstly; then a geometric model is reconstructed by using a bi-cubic surface...
Practice teaching is an important aspect of university professional building and the important way and mean of ensuring the quality of talents training. Based on analyzing the current employment status of higher education graduates and the problems that practice teaching of university computer professional are facing, we introduce the exploration of the reform ideas of university practice teaching...
Based on the summary of the teaching experience on “Computer Graphics”, this paper discusses the significance of visualization instruction and carries out the design and realization on visualization instruction of computer graphics algorithm. It includes generation of basic primitives, geometric transformations of these geometric objects, area filling, line clip and so on. At the same time the paper...
For the noise, blurry edge, bad contrast of the medical CT image, this article presents a medical CT image enhancing algorithm based on the mixture scope model of wavelet multi-scale transform. It uses wavelet multi-scale analysis to decompose the image signal to different direction sub-image, studies the different direction sub-pictorial information under the corresponding criterion by the different...
