aljabar bool method to make subtitute

The noises are one of the research topic in image processing. In digital images removal of gaussian noises using bilateral filter is performd in this file

自己编写的半功率带宽算法程序，可以用作参考，希望对大家有所帮助(I have written half-power bandwidth algorithm program can be used as a reference, we hope to help)

基于小波的图像压缩，采用就对了。自己运行过，效果还可以！(Image compression based on wavelet)

Code in matlab about Huffman Codification.

STEP模型读取的类库，官方资料，附文档说明(Read STEP model library, official data, with documentation)

根据对真空蒸发镀膜的分析，在40×40的范围内分别蒸 发：1000、5000、10000、20000、30000个粒子。  利用2维数组记录每个点的粒子数。  初始粒的横纵坐标为0～40的均匀分布。  能量为（15，3）的正态分布。  在基体表面自由行走时损失1的能量。  若该点有粒子，即与其他粒子相遇时损失3的能量。  由低处向高处扩散，每扩散一层，损失4的能量，由高处 向低处扩散，损失3的能量。  当粒子的能量小于等于0时停留下来，该点的粒子数加1。  临界核的尺寸为10个粒子。  根据每个点粒子个数的不同，以不同的灰度显示这些点。 点越亮，则表示该点的膜越厚。  以图形方式显示粒子初始能量的正态分布情况(Based on the analysis of the vacuum evaporation coating, respectively, in the range of from 4040 evaporated: 1000,5000,10000,20000,30000 particles.  each point using 2-dimensional array to record the number of particles. The  initial grains transverse and longitudinal coordinates of a uniform distribution of 0 to 40.
