Hello everybody. im working on Facial Expression recognition and iam in training step. During the feature Extrectaction using Gabor Filter no error but i got no result in my image(white image). this is my program:
faceDatabase=imageSet('Database');
personToQuery=1;
galleryImage=read(faceDatabase(personToQuery),1);
figure;
for i=1:size(faceDatabase,2)
imageList(i)=faceDatabase(i).ImageLocation(5);
end
out = [];
for scala = [0.10 0.20 0.30];
imgreduced = imresize(galleryImage,scala,'bilinear');
size(imgreduced)
for angolo=0:45:180
[G,gabout] = gaborfilter(imgreduced,2,4,16,deg2rad(angolo));
gabout
imshow(uint8(gabout));pause;close all;clc;
vettore = gabout(:);
vettore = vettore(1:25:end);
out = [out; vettore(:)];
end
end
can someone help me figure out which step or value i have to change or input to have a result of my feature extraction? thank in advance.
