Plsss help me to solve this error???
Traindatabasepath='E:\PROJECT2\original\appleleaves\ceder';
Trainfiles=dir(Traindatabasepath);
Trainnum=0;
for ii=1:size(Trainfiles,1)
if not(strcmp(Trainfiles(ii).name,'.')|strcmp(Trainfiles(ii).name,'..')|strcmp(Trainfiles(ii).name,'Thumbs.db'))
Trainnum=Trainnum+1;
end
end
imgccount=1;
for imgn=1:Trainnum
img=imread(strcat(Traindatabasepath,'\',num2str(imgn),'.jpg'));
% imshow(i);
% j=imresize(i,[256 256]);
% figure,imshow(j);
[r c]=size(img);
%global feature extraction
HSV=rgb2hsv(img);
H=HSV(:,:,1);
S=HSV(:,:,2);
V=HSV(:,:,3);
HM=mean(H(:));
SM=mean(S(:));
VM=mean(V(:));
k=1;
[r1 c1]=size(H);
for m=1:8:r1-7
for n=1:8:c1-7
BH=H(m:m+7,n:n+7);
BS=S(m:m+7,n:n+7);
BV=V(m:m+7,n:n+7);
BHM=mean(BH(:));
BSM=mean(BS(:));
BVM=mean(BV(:));
BMN=[BHM BSM BVM]';
BMEAN(k,:)=BMN;
k=k+1;
end
end
IH=zeros(k-1,1);
IS=zeros(k-1,1);
IV=zeros(k-1,1);
for p=1:k-1
if (BMEAN(p,1)>=HM)
IH(p)=1;
end
if (BMEAN(p,1)>=SM)
IS(p)=1;
end
if (BMEAN(p,3)>=VM)
IV(p)=1;
end
end
% IHSV=[IH IS IV]';
%IHSVMEAN(imgn,:,:)=IHSV;
IHSV=[IH' IS' IV'];
IHSVMEAN(imgn,:)=IHSV;
end
save colorlocal IHSVMEAN

Your images are not all the same size.
Note:
[r c]=size(img);
is probably a mistake. You do not use r or c so you might as well remove the line.
At that point in the code, img is an RGB image, so it has 3 dimensions. When you ask for only two outputs, the second output is number of columns times number of color planes -- the product of the outputs from size() is always equal to the number of elements in the array.
