SVM classifier with sliding window

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
