优化 Bitmap的小程序 希望对大家有用我人有很有借鉴意义(Optimize the Bitmap small program hope useful for everyone I have a lot of reference)

THE ALGORITH OF RGB TO HSV USE MATLAB

不错的源代码，喜欢matlab实验的朋友可以下载下来看看：） --模拟小球下落(Good source code, like matlab experiment to see if a friend can download it:) simulation of the fate of small ball)

雷达截面积————————矩形平板的后向散射RCS( backscatter RCS of Rectangular plate )

能够读取二维码，经过改造可以为己所用~~~~~~(The ability to read two-dimensional code, revamped for their own use ~ ~ ~ ~ ~ ~)

说明：  一本关于卡尔曼滤波器的英文文章的翻译版本，介绍的很详细具体，而且是翻译版本，读起来很方便。(A Kalman filter on the translation of the English version of the article, described a very detailed and specific, but also translation, easy read.)

系统辨识里面的梯度校正参数辨识方法，实用的系统辨识算法(System identification inside the gradient correction parameter identification methods, practical system identification algorithm)

HOLTEK触摸芯片BS84C12A-3库文件(HOLTEK touch chip BS84C12A-3 library files)

该代码仅计算了一个101×101尺寸的Gabor函数变换，得到均值和方差。代码采用两种卷积计算方式，从结果中可以看出，快速傅立叶变换卷积的效率是离散二维叠加和卷积的近50倍。 (The code is only the calculation of a 101 × 101 size Gabor function transformation, the mean and variance. Convolutional code using two methods of calculation can be seen from the results, fast Fourier transform convolution efficiency are two-dimensional discrete convolution superposition and nearly 50 times.)
