Hello Friends ,

please i have a question about how can I draw a slidingwindow with HOG descriptor

i am trying to do with but i stuck with..

this is my code

[r,c]=size(img)
z=zeros(r,c);
for nbr=1:r% r is the nbr of row of input image
    for nbc=1:c% c is the nbr of column of the input image 
%         imge2=readimage(imdsTest,2);
%         img2=rgb2gray(imge2);
        img3=imge2(g:g+10,f:f+12);% using input image size [g+10 f+12]
        histo=extractHOGFeatures(img3, 'CellSize', [2 2]); %extract hog features
        [pred ,scores]=predict(classifier,histo);%predictiin 
        if (string(pred)=='non_Stop')
           
            z(g,f)=-scores(2);
%             break;
        end
        f=1;
        g=g+1;
    end
    g=1;
    f=f+1;
end
