Maximum luminance as number output from falsecolor image

Hello,

I am currently trying to receive the maximum luminance values from falsecolour images in a number format. I know how to get the extrema printed on the falsecolor image, however I will have to analyze a high number of images, so manually typing them is not a solution for me.

Is there a command or a component where I can get the maximum luminance value for an image?

Best regards,

Florian

Hi Florian,

Do you have all the HDR images in the same folder? As Rob already answered in radiance mailing list you can use radiance pextrem command (http://radsite.lbl.gov/radiance/man_html/pextrem.1.html) to get the location and the value. Then you need to parse the output to get the max value and then store it in a text file. We don't have a component but this is an easy enough task to do if you know a little bit of scripting.
