Error in ImageClassifier (line 11)
Ftrain=db(:,1,2);
Test Image
[fname,path]=uigetfile('.jpg','Provide a Image for Testing');
c=strcat(path,fname);
im=imread(fname);
imshow(im);
title('Test Image');
%% Fond out which Class it Belongs to
Ftest=FeatureStatistical(im);
%% Compare with Database
load db.mat
Ftrain=db(:,1,2);
ctrain=db(:,3);
for(i=1:size(Ftrain,1))
dist(1,:)=sum(abs(Ftrain(1,:)-Ftest));
end

m=find(dist==Min,1);
det_class=ctrain(m);
msgbox(strcat('detected class',num2str(det_class)));
else
msgbox('Not Exist');

"db" can not be a matrix of dimension 3 (db(:,1,2)) and of dimension 2 (db(:,3)) at the same time. Use "size" to get the dimension of "db".
