segmentation using region growing in an image

经典数字水印算法，包括GUI实现 可直接运行(classic digital watermarking algorithm, including the realization of GUI can run)

快速傅里叶变换的C实现，采用新的倒序算法，程序代码只有一百多行，就要以实现千个采样点的计算(Fast Fourier Transform of C realized, the introduction of a new reverse algorithm, program code, only more than 100 lines, it is necessary to achieve the 1000 sampling points calculation)

用MATLAB编写的粒子滤波器程序，能很好对目标进行跟踪，适合学习粒子滤波器的同学。(Particle filter program written using MATLAB, well target tracking, suitable for students learning particle filter.)

MATLAB编写的增强图像分辨率的程序，可以提高图像分辨率，使图像更加清晰。(Written MATLAB program enhanced image resolution, image resolution can be improved to make the image clearer.)

说明：  在一幅图像中对单人脸进行定位,原理是基于多模板匹配(locate face in one picture in which there is a single face，its theory base on many templates matching)

画矩形的代码，包含各种算法，具体的自己看吧，这是图形处理的作业之一(Draw a rectangle of the code, contains a variety of algorithms, specifically for yourself, this is one of the graphics processing jobs)

System Generator中伪彩色增强建模(Pseudocolor enhancement model in the System Generator)

说明：  特征检测与匹配的目标是识别一个图像中的关键点与另一个图像中的对应 点之间的配对。(The goal of feature detection and matching is to identify the key points in one image and the corresponding points in another image)
