小波与计算机图形学

给出了在matlab环境下的源代码，经过了上机调试，可以实现小波变换对图像的二次压缩！-given Matlab environment in the source code, after the Machine, can achieve a wavelet transform of the second image compression!

这是对图像进行小波变换的源代码，使用者直接嵌入自己的代码中就可以了-This is an image wavelet transform source code, the user directly embed their own code can be a

基于Trous小波算法的影像融合由于存在抽取和插值运算，其结果存在一定的相位失真Trous小波算法通过有限滤波器内插近似实现对影像数据的无抽取离散小波变换较好地解决了上述问题，在阐述影像数据融合原理的基础上给出了基于Trous小波变换的影像融合处理方法和过程。-Trous wavelet algorithm based on image fusion because of extraction and interpolation operations, the result there is a certain degree of phase distortion trous wavelet algorithm through limited interpolation filter approximation of the image data to achieve without taking discrete wavelet transform can solve the above problems, Before going into the image data fusion based on the principle of give trous wavelet transform based image fusion methods and the process of treatment.

It contains very useful coding about three dimension spiht, which includes picture compression and video compression without motion-compensationa and motion-estimation.

ICA算法The algorithm is equivalent to Infomax by Bell and Sejnowski 1995 [1] using a maximum likelihood formulation. No noise is assumed and the number of observations must equal the number of sources. The BFGS method [2] is used for optimization. The number of independent components are calculated using Bayes Information Criterion [3] (BIC), with PCA for dimension reduction.-ICA algorithm:The algorithm is equivalent to Infomax by Bell and Sejnowski 1995 [1] using a maximum likelihood formulation.

图形动画特效演示程序，根据用户要求为一幅图片施加特效，可以产生非常美观的视觉效果。在制作软件的用户界面时，有一定参考价值。-Graphics animation special effects demo program, according to user requirements for the imposition of a special effects picture, you can have a very beautiful visual effects. In the production of software user interface, a certain reference value.

由于小波变换具有良好的时频分析特性，已经广泛应用于各种信号分析领域。由于小波变换算法的复杂性，如果直接计算小波变换，所需内存较大，耗时较长。尽管当今处理器芯片运算速度得到了大幅度的提高，但仍然在实时性上不能满足要求。为了简化计算过程，人们相继设计了一系列的快速算法来计算小波变换，以降低其运算次数。-Since the wavelet transform has good time-frequency analysis features, has been widely used in various fields of signal analysis. Wavelet transform algorithm as a result of the complexity, if the direct calculation of wavelet transform, the larger memory requirements, a longer time-consuming. Despite the computational speed of today
