contrast adjusment Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view. Because the human visual system is more sensitive to contrast than absolute luminance, we can perceive the world similarly regardless of the huge changes in illumination over the day or place to place. The maximum contrast of an image is the contrast ratio or dynamic range

SOM算法,matlab程序,是经典的教科书的例子程序,不错的源码(SOM algorithm, matlab program, is a classic textbook examples of procedures, good source)

两机五节点的仿真 可能有点错误 嘿嘿潮流分析的计算(Two five-node machine simulation may be a bit wrong hehe trend analysis calculations)

前后向平滑MUSIC算法。通过平滑，提高了分辨率(Before and after smoothing MUSIC algorithm. By smoothing to improve the resolution)

cosine和cosine平方加权的零点图。(Zero plots for cosine, cosine squared weightings)

测绘工程中常用的坐标转换代码，有WGS-xyz坐标系转经纬度、ENU坐标，有北天东坐标系转WGS-xyz、经纬度等(MAPPING commonly used coordinate transformation code, WGS-xyz coordinate system of latitude and longitude turn, ENU coordinate with the northern east coordinates turn WGS-xyz, latitude and longitude)

该代码是用分形技术来进行纹理分析及混沌序列来实现密写(The code is used fractal texture analysis techniques to conduct and chaotic sequence to achieve Steganography)

Multiwavelet wavelet theory has become a hot one, it is more than wavelet function and a number of scaling function to indicate signal. [1] using fractal interpolation function is the first of a multi-wavelet, as GHM Multiwavelets.
