I want to track 3 bubbles in videos(converted to GIF for uploading) like [![this][1]][1]
and append the x,y in vectors or lists for `cv::polylines`.
I can track if there is ONLY bubble in every frame and draw a track line for it with polylines but when I want to append ALL OF THEM in lists so I can select the bubbles I want, stuff goes WRONG.
I cant append the x and y of a bubble in its own vector.
code is simple but I made A CODE for anyone who needed the obvious code:
Mat frame,edgeFrame;
vector> cnts;
vector hie;
vector XY;
float r;
// specific vector for each bubble
vector firstBubble,secondBubble,thirdBubble,fourthBubble,millionthBubble;
while(true){
cap >> frame;
canny(frame, edgeFrame, 50, 150, 3);
findContours(edgeFrame, cnts, hie, CV_RETR_TREE, CV_CHAIN_APPROX_SIMPLE);
for(int i = 0 ; i < cnts.size() ; i ++){
minEnclosingCircle(cnts[i], XY, r);
circle(frame, XY , r , Scalar(0,0,0), 1 , LINE_AA);
// append the XY of contour to the specific list
//AKA the problem
}
}
to be more clear I want to draw from vectors like ***track lines:*** [![the GOal][2]][2]
P.S : one,two,three,four, ... is the name of vector.
this is not the only video that I want to track my bubbles.
bubbles are eggZaklty the same color and shape but the radius is not constant and it can be chaotic
***THE BUBBLES CAN MOVE HORIZONTALLY TOO***
EDIT:
Can I use something "like" optical flow on binary images?
***what I want is in lk_track in python examples***
