pcacode
程序设计步骤:
1、去均值
2、计算协方差矩阵及其特征值和特征向量
3、计算协方差矩阵的特征值大于阈值的个数
4、降序排列特征值
5、去掉较小的特征值
6、去掉较大的特征值(一般没有这一步)
7、合并选择的特征值
8、选择相应的特征值和特征向量
9、计算白化矩阵
10、提取主分量(Programming steps: 1 to mean 2, calculation of covariance matrix and its eigenvalues and eigenvectors 3, the calculation of covariance matrix eigenvalues greater than the threshold number of 4, in descending order of eigenvalue 5, remove the smaller eigenvalue 6, remove the larger eigenvalue (usually not this step) 7, the combined choice of eigenvalues 8, select the appropriate eigenvalues and eigenvectors 9, computing whitening matrix 10, principal component extraction)

rgb to HSV,很有用,调试成功,可以应用(rgb to HSV,#include "stdafx.h"
#include <iostream.h>
void main(float R, float G, float B, float& H, float& S, float&V)
{
// r,g,b values are from 0 to 1
// h = [0,360], s = [0,1], v = [0,1]
// if s == 0, then h =-1 (undefined)
float min, max, delta,tmp
tmp = R>G?G:R
min = tmp>B?B:tmp
tmp = R>G?R:G
max = tmp>B?tmp:B
V = max // v
delta = max- min
if( max != 0 )
S = delta/max // s
else
{
// r = g = b = 0 // s = 0, v is undefined

说明: :针对显微图像分析、识别需要的全自动控制显微镜,研究开发其相应的图像处理算法。提
出了能量谱自动聚焦评价函数算法、自适应选取基准图的图像拼接算法、改进 Laplacian算子的多层
聚焦图像叠合算法等。该算法模块已成功地应用于所开发的CMIAS 显微医学图像分析系统中,取得
了满意的应用效果。(【ABSTRACT】For the automatic microscope required by micro-image analysis and recognition, the
relevant image processing a lgorithms are investigated. Three algorithms are described: energy-spectrum
image auto focusing evaluation function, image merging based on the adaptive selection of standard image
and sum-modified-Laplacian (SML) operator for multi-focus image fusion. The algorithms have been
applied successfully to CMIAS medical micro-optical image analysis system and testified to be feasible
and effective. )
