我的图像上有一个滑动窗口。如果该窗口内的平均强度 > 210,则在该窗口上计算 GLCM 特征。如果 GLCM 功能满足 if 语句中的条件,则应在此滑动窗口周围绘制一个矩形。我已经使用以下代码进行了尝试,但是矩形不在图像上的正确位置。我不确定我是否将绘制矩形的代码放在了错误的位置,或者我是否输入了错误的坐标。任何人都可以帮我解决这个问题吗?
N2=8;
info2 = repmat(struct, ceil(size(Z, 1) / N2), ceil(size(Z, 2) / N2));
for row1 = 1:N2:size(Z, 1)%loop through each pixel in the 8x8 window
for col1 = 1:N2:size(Z, 2)
x = (row1 - 1) / N2 + 1;
y = (col1 - 1) / N2 + 1;
imgWindow2 = Z(row1:min(end,row1+N2-1), col1:min(end,col1+N2-1));
average2 = mean(imgWindow2(:));
window2(x,y).average=average2;
if average2>210
offsets0 = [0 1];
glcms = graycomatrix(imgWindow2,'Offset',offsets0);
stats = graycoprops(glcms,'all');
correlation=[stats.Correlation];
contrast=[stats.Contrast];
homogeneity=[stats.Homogeneity];
energy=[stats.Energy];
%if these conditions are met then this window contains an ROI
if (homogeneity > 0.9)
if (contrast<0.2)
if (energy>0.6)
%%show the ROI on the original image%%
Z1 = insertShape(Z, 'rectangle', [x y 32 32]);
figure(2);
imshow(Z1);
end
end
end
end % end if>210
end
end % window
