opencv车辆计数
通过opencv配置vs2012配置,实现读取视频并且进行车辆计数。用背景差分法能有效背景提取但是摄像头抖动必须控制。该代码运行前提是需要有相应背景图像进行差分。

Efficient Salient Region Detection with Soft Image Abstraction
资源描述Detecting visually salient regions in images is one of the fundamental problems in computer vision. We propose anovel method to decompose an image into large scale perceptually homogeneous elements for efficient salient region detection, using a soft image abstraction representation.
By considering both appearance similarity and spatial distribution of image pixels, the proposed representation abstracts out unnecessary image details, allowing the assignment of comparable saliency values across similar regions,and producing perceptually accurate salient region detection. We evaluate our salient region detection approach on the largest publicly available dataset with pixel accurate annotations. The experimental results show that the proposed method outperforms 18 alternate methods, reducing the mean absolute error by 25.2% compared to the previous best result, while being computationally more efficient.

基于c++的人脸识别
基于模板匹配操作比较简单,实现效果也是比较好的。该方法的主要思路是待检测图像与先前做好的模板图像之间提取的特征向量逐个进行比较,计算它们之间的相似度,然后将图像归于相应的类。本次实验使用的模板是trainImgs中的train20.dat文件先建立模板,然后 在计算待检测图像与模板之间的欧氏距离,与设定的阈值相比较,从而检测出该图像的人脸区域。#include "stdafx.h"#include "facedetect.h"#include "facedetectDoc.h"#include "facedetectView.h"#ifdef _DEBUG#define new DEBUG_NEW#undef THIS_FILEstatic char THIS_FILE[] = __FILE__;pDC->TextOut(600,10,"操作说明:");pDC->TextOut(600,40,"步骤一:载入训练库 *.dat 生成模板");pDC->TextOut(630,60,"(训练库在程序关闭前只需载入一次)");pDC->TextOut(600,80,"步骤二:载入 *.raw 或 *.txt/*.lst");pDC->TextOut(630,100,"如果载入的是 *.txt/*.lst 列表");pDC->TextOut(640,120,"按 Page Down/Up 翻页");pDC->TextOut(650,140,"(需要修改 *.txt/*.lst 里边的存放地址)");pDC->TextOut(650,160,"(注意存放地址不得出现中文或符号

FCM聚类算法
FCM算法是一种基于划分的聚类算法,它的思想就是使得被划分到同一簇的对象之间相似度最大,而不同簇之间的相似度最小。模糊C均值算法是普通C均值算法的改进,普通C均值算法对于数据的划分是硬性的,而FCM则是一种柔性的模糊划分
