i've a gray scale image and i've divided it into overlapping blocks.
each block i've stored in the form of vector in a matrix B.
From the matrix B ,i've calculated the MEAN, GLCM MEAN and ENTROPY MEAN of each and every blocks.
i want to create a new matrix having MEAN, GLCM MEAN and Entropy meaqn as three columns and number of rows same as B.
the code i wrote is:
for i=1:length(B) %Reading First Vector vector1=B(i,:); match1=i; block1=index(match1); rowstart1=startRow(match1); colstart1=startCol(match1); oneBlock1=grayImage(rowstart1:rowstart1+(blockSizeR-1),colstart1:colstart1+(blockSizeC-1));
%Calculating Mean mean1=floor(mean2(oneBlock1));
%Calculating GLCM Mean glcml1=0; glcmr1=0; glcm1=0;
glcm1=graycomatrix(oneBlock1); for x=1:overlapR for y=1:overlapC glcml1=glcml1+x*glcm1(x,y); glcmr1=glcmr1+y*glcm1(x,y); glcmLR1=abs(glcml1-glcmr1); end end glcmLRD1(index1)=glcmLR1; disp(glcmLRD1);
%Calculating Entropy entropy1=entropyfilt(oneBlock1); entropyMean1(index1)=floor(mean2(entropy1));
%Creating new matrix with 3 columns corresponding to Intensity Mean, GLCM Mean and Entropy Mean newB(index,1)=mean1 newB(index1,1)=glcmLR1 newB(index1,2)=entropyMean1; index1=index1+1; New(rowstart1 : rowstart1 + (blockSizeR - 1), colstart1 : colstart1 + (blockSizeC - 1),[1 2 3])=0; %assign black color end disp(newB);
here newB is my new matrix having columns mean glcm and entropy
but it shows error that the dimension mismatch..
plz help me in solving my problem..
