how to solve this error??? Subscripted assignment dimension mismatch. Error in traincolorceder (line 100) IHSVMEAN(imgn,:)=IHSV;

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.
