When I execeute the given matlab project I faces the follwoing error when i run the com.m file.I attached the full project file O.P Final.Please help me anyone how can i resolve this problem?
Error Occured:
Error using .*
Matrix dimensions must agree.
Error in comp (line 20)
FPimg = TestMask.*NotTargetMask;
%%% Here com.m file will be given
clc;
TargetImg=imread('tumor.jpg');
[L,path1]=uigetfile('*.jpg','select a input image');
str1=strcat(path1,L);
TestImg=imread(str1);
[u v]=size(TargetImg);
TPrate=zeros(1, u, 2);
FPrate=zeros(1, u, 2);
TargetMask = zeros(size(TargetImg));
TargetMask = TargetImg >0;
NotTargetMask = logical(1-TargetMask);
TestMask = zeros(size(TestImg));
TestMask= TestImg >0;
FPimg = TestMask.*NotTargetMask;
FP = sum(FPimg(:))
TPimg = TestMask.*TargetMask;
TP = sum(TPimg(:))
FNimg = TargetMask-TPimg;
FN = sum(FNimg(:))
TNimg = 1- FPimg;
TN =sum(TNimg(:))
TPrate(1,:,1)=TP/(TP+FN);
FPrate(1,:,1)=FP/(FP+TN);
Sensitivity(1)= TP/(TP+FN)*100
Specificity(1)= TN/(TN+FP)*100
Accuracy(1)=(TP+TN)/(TP+TN+FN+FP)*100
TargetImg(TargetImg>0)=200;
%2. set second image non-zero values as 300
TestImg(TestImg>0)=300;
%3. set overlap area 100
OverlapImage = TestImg-TargetImg;
%4. count the overlap100 pixels
[r,c,v] = find(OverlapImage==100);
countOverlap100=size(r);
%5. count the image200 pixels
[r1,c1,v1] = find(TargetImg==100);
TargetImg_200=size(r1);
%6. count the image300 pixels
[r2,c2,v2] = find(TestImg==200);
TestImg_300=size(r2);
Similarity_index=(2*TP)/(2*TP+FP+FN)*100

test.jpg and tumor.jpg are both 128 x 128, but all of the other files in the directory are 256 x 256. You cannot multiply a 128 x 128 with a 256 by 256.

The above screen shot does not show me how many rows and columns and panes that the variables have. It shows me the error message, but does not tell me how large the variables are.
