计算机视觉经典著作《计算机视觉中的多视图几何》配套代码(MATLAB and Octave Functions for Computer Vision and Image Processing)

实现了图像的加水印，去噪，加噪声等功能，基于kaiser窗的双谱线插值FFT谐波分析，用于建立主成分分析模型。( Realize image watermarking, de-noising, plus noise and other functions, Dual-line interpolation FFT harmonic analysis kaiser windows, Principal component analysis model for establishing.)

图像局部放大功能。包括主要的三个消息处理函数，由鼠标拖动画出需放大区域，松开即将图像局部放大到整个客户区，能够实现层层放大。(enlarge images partial function. Including the three main message processing function, the mouse scrolling painted by the need to enlarge the regional, Loosen the forthcoming local enlarge images of the entire client area, can be achieved at every level to enlarge.)

The code contains the method to extract minutiae and also to enhance the image

说明：  通过IDL，简单实现灰度变换，彩色变换等基本操作，包括图片打开保存拖拽显示(Simple implementation of gray level transformation, color transformation and other basic operations)

rgb在matlab中三个通道的子图显示，直方图 ，频谱图，高斯滤波后的图像显示(RGB in MATLAB, three channel subgraphs show histograms, spectrogram, and Gauss filtered image display)

自己写的用开闭眼模板法判断一个眼睛的开闭状态，前提是需要去定位眼睛(Wrote it myself with open eyes closed, a template method to determine the state of opening and closing the eyes, the premise is the need to positioning the eyes)

说明：  灰度图像二值化及目标提取和质心求取,Matlab代码.对初学者学习有用(Gray image binarization and target extraction and center of mass strike, Matlab code. Learn useful for beginners)

利用PCA检测图像的复制粘贴区域。检测效果良好。(PCA was used to test digital image s copy and paste area.)

全息图的建立与重现 比较简单 但是有说明 比较容易懂(The establishment and reproduce hologram is relatively simple but relatively easy to understand instructions)
