LDA

一种新型的基于Tucker张量分解的高光谱图像降噪算法，性能优于传统的维纳滤波(a novel method based on Tucker decomposition for HSI denoising)

利用双线性插值，获取亚像素位置的灰度值。适用于得到sift、surf得到的特征点坐标处的灰度值获取(The gray value of sub-pixel position is obtained by bilinear interpolation)

基于最小矩方判断灰度重心法计算光心位置的像素点，并输出结果。(Analyzing calculate pixel gray scale optical center position the center of gravity method, and the output torque based on the minimum square.)

harris角点检测以及NCC特征匹配MATLAB代码(Harris corner detection and NCC feature matching MATLAB code)

指纹识别系统，包括指纹图像预处理，特征点提取，采用点模式匹配。(Fingerprint identification systems, including fingerprint image preprocessing, feature extraction, using point pattern matching.)

本程序是基于Matlab的米粒图像的分割、计数以及周长、面积、形状因子等参数的计算。图像分割是基于腐蚀膨胀算法，选用边界跟踪法计算周长，程序代码清晰明了，对于参数的计算速度较快，且参数计算精度较高。(This procedure is based on the Matlab image segmentation grain of rice, counting and perimeter, area, shape factor and other parameters of the calculation. Image segmentation is based on the corrosion expansion algorithm, the choice of boundary tracking method perimeter, code clarity, the parameter calculation is faster and higher precision parameters.)
