I am a new user of OriginPro 8.5 and I need a quick and easy way to find the maximum value in a matrix which represents an image. Any ideas? Thanks. |

Suppose I have two images in MBook1 in Matrixsheets "Capture1" and "Flowers". This script gets those values:
range rm1 = [MBook1]Capture1!1;
range rm2 = [MBook1]Flowers!1;
stats rm1;
stats.max=;
stats rm2;
stats.max=;
Note that if the image is RGB, you will get back an RGB value, otherwise you get an N-bit gray scale value.
Not using a script, you would have to use Analysis : Histogram,
then:
For gray scale images, you would have to find the last row for which Histogram Master is non-zero.
For RGB you can do the same per channel.
