I successfully used -verbose to find median RGB values for 1 .jpg file.
Next step is finding median RGB values for about 2000 .jpg files.
Id like to figure out how to do this automatically rather than one at a time.
Id also like to figure out how to export the data resulting from -verbose over 2000 files to something like .csv or .txt.
Does anyone know how to best approach this?
这将为您提供当前工作目录中所有 .jpg 图像的所有详细信息：
识别 -verbose *.jpg >verbose.txt
如果你在 Unix 系统上，这个会转储到 verbose.txt 行filename => overall RGB mean value：
*.jpg 中的 f；做 echo "$f => `identify -verbose "$f" | grep mean | tail -n1 | cut -d':' -f2 | xargs`"; 完成 >verbose.txt
这将转储到 verbose.txt 行filename => R = mean value, G = mean value, B = mean value：
*.jpg 中的 f；做 echo "$f => `identify -verbose "$f" | grep mean | head -n3 | cut -d':' -f2 | xargs | awk '{print "R = "$1" "$2", G = "$3" "$4", B = "$5" "$6}'`"; 完成 >verbose.txt
