我正在做一个使用图像处理技术来识别不同对象及其长度的项目.我在javaCV和OpenCV中经历了很多例子.但不幸的是我无法识别多边形的T形.
我尝试使用以下矩形识别方法,但我失败了.
public static CvSeq findSquares( final IplImage src, CvMemStorage storage)
{
CvSeq squares = new CvContour();
squares = cvCreateSeq(0, sizeof(CvContour.class), sizeof(CvSeq.class), storage);
IplImage pyr = null, timg = null, gray = null, tgray;
timg = cvCloneImage(src);
CvSize sz = cvSize(src.width() & -2, src.height() & -2);
tgray = cvCreateImage(sz, src.depth(), 1);
gray = cvCreateImage(sz, src.depth(), 1);
pyr = cvCreateImage(cvSize(sz.width()/2, sz.height()/2), src.depth(), src.nChannels());
// down-scale and upscale the image to filter out the noise
cvPyrDown(timg, pyr, CV_GAUSSIAN_5x5);
cvPyrUp(pyr, timg, CV_GAUSSIAN_5x5);
cvSaveImage("ha.jpg", …这段代码行的含义是什么？如何将此代码转换为javacv？
gray = Scalar::all(255);
这是与此代码行相关的整个代码.
Mat src = imread("in.jpg"), gray;
cvtColor(src, gray, CV_BGR2GRAY);
threshold(gray, gray, 230, 255, THRESH_BINARY_INV);
vector<Vec4i> hierarchy;
vector<vector<Point> > contours;
findContours(gray, contours, hierarchy, CV_RETR_LIST, CV_CHAIN_APPROX_SIMPLE);
gray = Scalar::all(255);
有人可以解释一下吗？
