SVM classifier with sliding window
显示 更早的评论
Helloo!!
I am working on detecting eyes open or close by using SVM classifier with HOG feature and there is problem in running the sliding window and do not know what is the mistake.
as you see the code below , i have already trained SVM classifier.
can anyone help me! please
code:
load classifier
imdsTest = imageDatastore('TestImages');
testImg = readimage(imdsTest,1);
figure,
imshow(testImg)
title('Test Image');
%%
s = 5;
w = 100;
h = 40;
[r,c] = size(testImg);
H = zeros(r,c);
r = floor((r-h)/s)+1;
c = floor((c-w)/s)+1;
%%
r1 = 1;
c1 = 1;
for n=1:r
for m=1:c
img = testImg (c1:c1+39,r1:r1+99);
%imshow(img)
hog1 = extractHOGFeatures(img,'CellSize',[2,2]);
[pred,scores] = predict(classifier,hog1);
if (string(pred) == 'closedEye')
pause(1);
H(c1,r1) = - scores(2);
end
r1 = r1+s;
end
r1 = 1;
c1 = c1 +s;
end
[rw,c1]= find(H>0.75);
figure,
imshow(testImg)
title('closed eye Detection')
for d=1:length(rw)
pasue(1)
imrect(gca, [c1(d), rw(d),100,40]); %
end
