If stats was created by calling regionprops, then the field name should be Solidity with a capital S.

在 MATLAB Online 中打开

brain2.jpg

clear all 
clc
close all
img=imread('brain2.jpg');
bw=imbinarize(img , 0.9);  %Thresholding value  if less than 0.7 color is black ,if morr than 0.7 color is white
label=logical(bw); %area of tumor
stats =regionprops(label,'Solidity','Area'); %healthy region
denisty=[stats.Solidity];
area=[stats.Area];
high_dense_area = denisty > 0.5 ;  %Area of tumor
max_area=max(area(high_dense_area));    %max area 
tumor_label=find(area==max_area); %place of tumor
tumor = ismember(label,tumor_label);
s=strel('square',4);
tumor=imdilate(tumor,s);
figure;
subplot(1,3,1);imshow(img,[ ]);title('Brain' );
subplot(1,3,2);imshow(tumor,[ ]);title('Tumor alone' );
[B,L]=bwboundaries(tumor,'noholes');
subplot(1,3,3);imshow(img,[])
hold on 
for i=1:length(B)
    Plot(B{i}(:,2),B{i}(:,1),'Y','lenewidth',1.45)
end
title('Detected image')
hold off

this is my code dosenot run correctly what i miss in this code and it is one of optimal image attach the vidio with it

Expected input number 1, BW, to be two-dimensional. Error in bwlabel (line 65) validateattributes(BW, {'logical' 'numeric'}, {'real', '2d', 'nonsparse'}, ... Error in tumor2 (line 6) label = bwlabel(logical(bw)); %area of tumor
