输入一组数据，xy值，用来拟合椭圆。只要改变输入数据，该代码就可以直接使用。另附上椭圆拟合算法。(Enter a set of data, xy values, used to fit ellipses. Just change input data, the code can be used directly. Attached on the ellipse fitting algorithm.)

有时为了方便处理，我们需要对大量的图像格式进行转换，本程序就是对图像格式批量转换。(Sometimes in order to facilitate the image processing, we need to tranfer the format of a lot of images.This program is to tranfer the image format in batches.)

一个作业,用matlab实现指纹识别，做得不好，惭愧(an operation using Matlab achieve fingerprint identification, is not done properly ashamed)

彩色图像边缘检测（canny 算子，高斯窗口可调）(image edge detection [canny])

采用hough变换检测仪表的指针位置，但是易受背景、边缘直线的干扰(The Hough transform is used to detect the position of the pointer, but it is vulnerable to the interference of background and edge lines.)

说明：  对数据的独立性进行分析，对数据的预处理（中心化和白化处理）(The independence of data analysis, data pre-processing (center-based and the whitening process))

matlab代码 用改进的八点算法求基础矩阵，进而求本质矩阵及相机外参。(improve eight)

说明：  基于稀疏表达的多源图像数据融合，遥感图像融合(Multi-source image data fusion based on sparse expression, remote sensing image fusion)

数字图像隐藏及提取研究分析论文、文献等。主要研究算法为LSB算法和DCT奇偶量化、DCT均值量化。(Digital Image Information Hiding and Extraction of analytical papers, literature. The main algorithm for the LSB algorithm and DCT parity quantization, DCT mean quantization.)

利用霍夫变换进行椭圆检测，无需模板，不同的图片只需要更改个别参数(Ellipse detection using Hough transform, without templates, a different picture only need to change individual parameters)
