Is there a function in OpenCV that does same function as Matlab Vision.blobAnalysis()? -

-

our target linux on embedded system cannot run matlab. have computer vision matlab script prototypes, , want functionality (vision.blobanalysis) ported embedded.

two options: use matlab coder port matlab computer vision functionality embedded, or reproduce functionality using opencv on embedded system.

try simple blob detector:

using namespace cv; // read image mat im = imread( "blob.jpg", imread_grayscale );  // set detector default parameters. simpleblobdetector detector;  // detect blobs. std::vector<keypoint> keypoints; detector.detect( im, keypoints);  // draw detected blobs red circles. // drawmatchesflags::draw_rich_keypoints flag ensures size of circle corresponds size of blob mat im_with_keypoints; drawkeypoints( im, keypoints, im_with_keypoints, scalar(0,0,255), drawmatchesflags::draw_rich_keypoints );  // show blobs imshow("keypoints", im_with_keypoints ); waitkey(0);
