Hello,
I have a video of someone who has an orange in his hand and my goal is to track this orange. First of all i have to create a ROI around this orange after the segmentation:
Left: the original video , Right: the video with segmentation to just have the orange.
Left: The ROI around the orange, Right: The virtual camera who follows the orange thanks to the ROI.First of all i read the video and after, with a while, i must detect the orange in each frame:
videoFileReader = VideoReader('VT.mp4');;
VideoPlayer = vision.VideoPlayer('Position',[100,100,1920,1080]);
while hasFrame(videoFileReader)
videoFrame = readFrame(videoFileReader);
Bin=videoFrame(:,:,1);
frame_binarise=imbinarize(Bin);
surface=sum(sum(frame_binarise));
[X_barycentre, Y_barycentre] = calcul_Barycentre(frame_binarise);
X=floor(X_barycentre);
Y=floor(Y_barycentre);
se = strel("diamond",1);
contour = frame_binarise - imerode(frame_binarise,se);
imshow(frame_binarise);
end
My baryencenter function:
function [X_barycentre, Y_barycentre] = calcul_Barycentre(img)
[LIG,COL]=size(img);
S = sum(sum(img));
sumX = 0;
for l=1:1:COL
sumX = sumX+l*sum(img(:,l));
end
X_barycentre = sumX/S;
sumY = 0;
for k=1:1:LIG
sumY = sumY+k*sum(img(k,:));
end
Y_barycentre = sumY/S;
So my probleme is how to make the ROI around the orange ?
