validation of goal post by using FE

说明：  图像分类中的交叉验证方法，比如说，一个训练集集合，为了得到其中参数的较准确值，就可以使用此类算法(Image Classification Based on cross-validation method, for example, a collection of training set, in order to obtain more accurate values of these parameters, you can use these algorithms)

this program is useful for spectral colour

利用外接矩形描述人体目标，在Matlab里实现跌倒检测。(Using external rectangle describes human target, realize the fall detection in Matlab. )

用matlab实现动画的制作，三维、二维制图，图像处理。。。。(Animation, drawing. . .)

grain detection used to detect the kind of grain

cheby1 bpf @ wav file

it is a program of modultion & demodulation of voice signal

实现爆炸碎块的轨迹分析，并求出碎块的落地点画图表示……(Realize the explosion of fragments path analysis, and get the pieces fell site drawing that...... )

第一：边界加强，通过估计噪声和实际信号的比值，来确定各个尺度的细节系数，以达到噪声抑制和边界加强。第二，通过对小波分解的近似部分进行直方图均衡，达到加大整幅图片的对比度，而不太影响细节的目的。(First: to strengthen the border, through the estimates and the actual signal noise ratio, to determine the details of each scale factor, so as to achieve noise suppression and boundary strengthening. Secondly, the wavelet decomposition of the approximate portion of histogram equalization to increase the contrast of the whole images, and do not affect the details of the purpose.)
