jpegFiles = dir('*.jpg');
numfiles = 162;
mydata = cell(1, numfiles);
T = table((1:162)', zeros(162,1), 'VariableNames', {'Serial_No.', 'meanLuminance'})
for k = 1:numfiles
mydata{k} = imread(jpegFiles(k).name);
RGB = imread(jpegFiles(k).name);
graying = rgb2gray(RGB);
meanLuminance = mean(graying,"all")
T{k,2} = meanLuminance;
end
162枚の画像の1枚ずつの平均輝度を計算し、それを表にしたいのです。しかし、上のコードでは、162×2の行列の表は作れたのですが、meanLuminanceのところに平均輝度の計算結果が表示されず、困っています。よろしくお願いします。

@suzuka iwaki, It would be better if you respond to the answer(s) given, instead of asking a new question. https://in.mathworks.com/matlabcentral/answers/2039391-?s_tid=prof_contriblnk
