基于J2ME的PNG图片文件处理源程序 这里所说的PNG图片文件处理是指剔除掉PNG文件中的非关键数据段,从而达到压缩文件大小的目的。该程序为控制台程序，只需在控制台窗口执行jar即可。-J2ME Based on the PNG image file mentioned here deal with source PNG image file is the deal with PNG files to weed out non-critical data in the paragraph, so as to achieve the purpose of the size of compressed files. The program procedures for the console, just in the console window to the implementation of jar.

Description: Recent studies on Mathematical modeling of visual cortical cells [Kulikowski/Marcelja/Bishop:1982] suggest a tuned band pass filter bank structure. These filters are found to have Gaussian transfer functions in the frequency domain. Thus, taking the Inverse Fourier Transform of this transfer function we get a filter characteristics closely resembling to the Gabor filters. The Gabor filter is basically a Gaussian (with variances sx and sy along x and y-axes respectively) modulated by a complex sinusoid (with centre frequencies U and V along x and y-axes respectively).

可实现与graph-cuts算法相似的图像分割效果. 他借用了生物形态学知识，将每一个像素视为一个细胞，这些细胞可能是前景，背景，或其他。这些细胞依据其灰度竞争获得生长，由此获得分割。-This algorithm is presented as an alternative to graph-cuts. The operation is very simple, and can be thought of with a biological metaphor: Imagine each image pixel is a "cell" of a certain type. These cells can be foreground, background, undefined, or others. As the algorithm proceeds, these cells compete to dominate the image domain. The ability of the cells to spread is related to the image pixel intensity
