说明：  MPCA一个博士编写的多线程pca变换方法，内含发表论文(Dr. MPCA prepared a multi-threaded PCA transform methods, including papers)

这是一个灰度图像进行哈夫曼编码的Matlab程序，包括编码和解码部分。绝对能用！(Huffman Code)

imx377 手册 imx377 datasheet imx377 datasheet(imx377datashee, imx377datasheet,imx377datasheet)

给出已有图片中小球的个数。（图中有很多很多个）(Picture has been given the number of small balls. (Chart There are many, many months))

现有大屏拼接技术性能参数对比，这是我上个月的调研内容，数据可信，对于要了解大屏拼接技术的人一定有帮助(Existing large-screen display technical performance parameters comparison, this is my last month s survey content, data credibility, for large-screen technology to understand who must have help)

说明：  1、正弦函数 f (t) = K sin(wt +a) 2、矩形脉冲函数 f (t) = u(t) - u(t - t0 ) 3、抽样函数 4、单边指数函数 f (t) = Ke -t 5、已知信号 f1(t) = u(t + 2) - u(t - 2)， f 2 (t) = cos(2pt) ，用 MATLAB 绘制 f1(t) + f 2 (t) 和 f1(t)′ f 2 (t)的波形。(such as : Sine function f (t) = K sin(wt +a) Rectangular pulse function f (t) = u(t)-u(t-t0) Sampling function One-sided exponential function f (t) = Ke -t Known signal f1(t) = u(t + 2)-u(t-2), f 2 (t) = cos(2pt), draw with MATLAB The waveforms of f1(t) + f 2 (t) and f1(t)*f 2 (t))

说明：  使用MATLAB求图像的形状特征-7个不变矩，亲自测试过可以用(Using MATLAB to find the shape feature of the image - 7 invariant moments, which have been tested and used personally.)

可用于简单图像的处理及几何特征提取，可得到1. 长宽比 2. 矩形度 3. 圆形度 4. 面积凹凸比 5. 周长凹凸比 6. 球形度 7. 偏心率 8. 形状参数(It can be used to process simple images and extract geometric features. It can obtain 1. aspect ratio 2. rectangularity 3. roundness 4. area concave-convex ratio 5. circumference concave-convex ratio 6. sphericity 7. eccentricity 8. shape parameters.)

可以采用形态学方法找出边界，比较有益的初学者的学习方法。(It s very good for a newer to learning about image processing.)

实图像的纹理特征提取，提取出的效果比较好，希望能够绑到有用的同学和人员(Real image texture feature extraction, the effect is better, hoping to be tied to useful classmates and personnel.)
