是否有任何版本的CvBlobs库使用cv :: Mat？ [英] Is there any version of CvBlobs library which works with cv::Mat?

问题描述

我刚刚发现了 CvBlobsLib ，它可以是一个祝福，但它可悲的使用IplImage。

有没有机会有一个新的cv :: Mat风格的版本，我不会碰巧找到它？

I have just discovered CvBlobsLib that can be a bless but it sadly uses IplImage.
Is there any chance that there is a new cv::Mat-style edition I just don't happen to find it?

编辑：

原来，我碰巧发现了2个不同的库，CvBlobsLib和CvBlobs，yeehaa。 :)

我看到CvBlobsLib比cvBlobs更少使用，那不是在opencv willowgarage，而是在google代码。我欢迎两个图书馆的答案，虽然，因为两个工作与IplImage。 ：）

It turned out that I happened to discover 2 distinct libraries, CvBlobsLib and CvBlobs, yeehaa. :)
I saw CvBlobsLib is less used than cvBlobs, that is NOT on opencv willowgarage but on google code. I welcome answers for both libraries, though, as both work with IplImage. :)

推荐答案

编辑：我说的是 cvBlobs 在这个答案，对不起，我搞砸了 cvBlobsLib ...

I'm talking about cvBlobs in this answer, sorry that I messed it up with cvBlobsLib ...

我一直在找这个，

但实际上你总是可以这样做： IplImage iplImg = mat; ，只需使用& iplimg ，无论您需要 IplImage * 。

But actually you can always do this: IplImage iplImg = mat; and just use &iplimg wherever you need an IplImage*.

我在一些项目中使用了 cvBlobs 这种方式：

I used cvBlobs this way successful in a few projects:

#include <cvblob.h>
using namespace cvb;

// load image
cv::Mat mat = cv::imread("image.jpg");

// convert cv::Mat to IplImage
IplImage img = mat;

// convert to grayscale
IplImage *gray = cvCreateImage( cvGetSize(&img), IPL_DEPTH_8U, 1 );
cvCvtColor( &img, gray, CV_BGR2GRAY );

// get binary image
cvThreshold( gray, gray, 150, 255, CV_THRESH_BINARY );

// get blobs
IplImage *labelImg = cvCreateImage( cvGetSize(gray), IPL_DEPTH_LABEL, 1 );
CvBlobs blobs;
unsigned int result = cvLabel( gray, labelImg, blobs );

// render blobs in original image
cvRenderBlobs( labelImg, blobs, &img, &img );

// *always* remember freeing unused IplImages
cvReleaseImage( labelImg );
cvReleaseImage( gray ); 

// convert back to cv::Mat
cv::Mat output( &img );
