Everytime i focus my camera to banana is lag or pause until 36 seconds. How to reduce time or remove lag for execution.
HERE IS MY CODE:
while true
tic;
picture = camera.snapshot;
picture = imresize(picture,[227,227]);
label = classify(nnet, picture);
toc;
tic;
image(picture);
toc;
tic;
if label == 'banana'
set(handles.edit1, 'ForegroundColor', 'green', 'string', '+ YES');
toc;
tic;
bel = res_train_classes(picture);
toc;
tic;
if bel == 'A' || bel == 'B'
set(handles.edit2, 'ForegroundColor', 'green', 'string', '+ YES');
set(handles.edit3, 'ForegroundColor', 'green', 'string', bel);
toc;
tic;
diff_im = imsubtract(picture(:,:,2), rgb2gray(picture));
diff_im = medfilt2(diff_im, [3 3]);
diff_im = imbinarize(diff_im,0.18);
diff_im = bwareaopen(diff_im,300);
bw = bwlabel(diff_im, 8);
stats = regionprops(bw, 'BoundingBox', 'Centroid');
toc;
tic;
imshow(picture)
toc;
tic;
hold on
parfor object = 1:length(stats)
bb = stats(object).BoundingBox;
bc = stats(object).Centroid;
rectangle('Position',bb,'EdgeColor','g','LineWidth',2)
plot(bc(1),bc(2), '-m+')
a=text(bc(1)+15,bc(2), strcat('X: ', num2str(round(bc(1))), ' Y: ', num2str(round(bc(2)))));
set(a, 'FontName', 'Arial', 'FontWeight', 'bold', 'FontSize', 12, 'Color', 'yellow');
end
toc;
hold off
drawnow limitrate;
tic;
if ~isempty(stats)
set(handles.edit4, 'ForegroundColor', 'green', 'string', '+ YES');
else
set(handles.edit4, 'ForegroundColor', 'red', 'string', '- NO');
end
toc;
tic;
a = blacked_background(picture);
imshow(a);
drawnow limitrate;
toc;
tic;
% grayImage = picture;
% [rows, columns, numberOfColorChannels] = size(grayImage)
% if numberOfColorChannels > 1
% grayImage = rgb2gray(grayImage);
% end
% toc;
%
% binaryImage = grayImage == 0;
% binaryImage = imclearborder(binaryImage);
% [labeledImage, numBlobs] = bwlabel(~im2bw(binaryImage,0.7));
% coloredLabels = label2rgb (labeledImage, 'hsv', 'k', 'shuffle');
% total_bk_spots=numBlobs-1
% props = regionprops(labeledImage, 'BoundingBox', 'Centroid');
%
% imshow(a);
% hold on;
% for k = 1 : numBlobs
% bb = props(k).BoundingBox;
% bc = props(k).Centroid;
% rectangle('Position',bb,'EdgeColor','c','LineWidth',2);
% end
% drawnow limitrate;
% hold off
tic;
grayImage = a;
[rows, columns, numberOfColorChannels] = size(grayImage);
toc;
tic;
if numberOfColorChannels > 1
grayImage = rgb2gray(grayImage);
end
toc;
tic;
hp = impixelinfo();
binaryImage = grayImage == 0;
binaryImage = imclearborder(binaryImage);
[labeledImage, numBlobs] = bwlabel(~binaryImage);
coloredLabels = label2rgb (labeledImage, 'hsv', 'k', 'shuffle');
props = regionprops(labeledImage, 'BoundingBox', 'Centroid');
toc;
tic;
imshow(picture);
hold on;
toc;

parfor k = 1 : numBlobs

set(handles.edit5, 'ForegroundColor', 'r', 'string',numBlobs);

set(handles.edit5, 'ForegroundColor', 'green', 'string', '- NONE');
end
toc;

if isempty(numBlobs) && ~isempty(stats) && numBlobs > 1
title('Accepted');
h = waitbar(0,'ACCEPTED');
steps = 1000;
parfor step = 800:steps
waitbar(step / steps)
end
close(h)
else
title('Reject');
h = waitbar(0,'REJECT');

parfor step = 800:steps
waitbar(step / steps)
end
close(h)
end
toc;

Do I read that correctly, that every time a banana is detected, that you start a parfor? I do not see a parpool creation anywhere, so the first time in the session you do that, there would be a delay while the pool was created.
