Hi All,
I'm trying to store mergerd image (imfuse) which include two lines (yellow and blue) - see script below.
Does anyone has an idea how to store this image without using "insertShape" function from CV toolbox?
Thank you,
Miki
for i=1:len
background = imread(FileList(i).name);
[name,~] = strsplit(FileList(i).name, '.');
original_gray = read(vid, str2num(char(name(1))));
original_gray = imrotate(original_gray,90);
original_gray = rgb2gray(original_gray);
pair = imfuse(original_gray, background, 'blend');
output1 = insertShape(pair,'Line',[g_lx_vec(i),g_ly_vec(i),nozzle_l(1),nozzle_l(2)],'Color', {'Yellow'},'LineWidth',5);
output2 = insertShape(output1,'Line',[g_rx_vec(i),g_ry_vec(i),nozzle_r(1),nozzle_r(2)],'Color', {'Blue'},'LineWidth',5);
imwrite(output2, fullfile(dest_folder, sprintf('%01d.jpg', i+9000)));
end

Hi,
Instead of using insertShape you can show the current image on a figure using imshow and then can use plot to draw the lines on same figure. Also, for saving the current figure with only image as output you can use imwrite and getframe. You may find code with changes mentioned useful.
pair = imfuse(original_gray, background, 'blend');
figure,imshow(pair);
hold on
plot([g_lx_vec(i),nozzle_l(1)],[g_ly_vec(i),nozzle_l(2)],'Color','yellow','LineWidth',5);
plot([g_rx_vec(i),nozzle_r(1)],[g_ry_vec(i),nozzle_r(2)],'Color','blue','LineWidth',5);
imwrite(getframe(gcf).cdata, fullfile(dest_folder, sprintf('%01d.jpg', i+9000)));
close(gcf);
