说明：  二维原始Otsu算法的MATLAB实现和其对应的文献。实现效果很好。(MATLAB realization of two-dimensional original Otsu algorithm and its corresponding literature. To achieve good results.)

逆透视变换的数学原理，在文档中有详细的逆透视变换的矩阵推导过程，但是没有代码，opencv逆透视变换代码可以看我发的另一篇资源。。。。。。。。。。。。。。。。。。(The mathematical principle of reverse perspective transformation, in the document there is a detailed matrix rendering process of the inverse perspective transformation, but there is no code, opencv reverse perspective transformation code can see another resource I sent)

这是个由matlab仿真实现的基于dwt的数字水印技术算法，实现了数字水印的嵌入、提取和一系列攻击实验。效果良好。(This is implemented by the matlab simulation of digital watermarking technique based on dwt algorithm, realization of the digital watermark embedding, extraction and a series of attacks on experiments. Good effect.)

单像素相机是基于压缩传感理论实现的，是数码相机发展的另一个革命性的方向，包括了所有单像素前沿的文献(Single-pixel camera is based on compressed sensing theory to achieve, is another revolutionary development direction of digital cameras, including the literature of all single-pixel frontier)

图形学中的透视投影算法 在屏幕中心绘制立方体的透视投影 可以绘制一点透视图 二点透视图 三点透视图(Graphics in the perspective projection algorithm for drawing a cube in the center of the screen you can draw a little perspective projection perspective two point perspective three-point perspective)

用 双 线 性 插 值 法 实 现 图 像 缩 放(Using bilinear interpolation for image zooming)

医学图像 CT/MR 图像的融合算法 使用梯度频率对两图像进行增强并融合，代码运行良好，适合初学者学习（注意无配准功能）(Medical image CT/MR image fusion algorithm uses gradient frequency to enhance and fuse two images, the code runs well, suitable for beginners to learn (pay attention to no registration function))

完成机器视觉里反透视变换功能，可以确定敢兴趣区，确定图像到实际道路的分辨率(completion of the anti-machine vision Lane perspective transformation function, it is possible to identify am interested in the district to determine the actual images of the road resolution)

图形验证码识别引擎 V1.1 可以识别数字(Graphics Recognition Engine Code V1.1)

说明：  用2种方法，对text.png图像中的字母‘a’进行定位，给出定位结果以及位置坐标。(Two methods were used to locate the letter 'a' in the image of text. PNG, and the location result and position coordinates were given.)
