Dear list, I am trying to glare analysis via HDR images captured by a canon DSLR Camera and sigma fish eye lens.
The procedure that I use was 1. Taking 13 images via gphoto2 +Crontab 2. Creating HDR images in HDRgen 3. Resize pfilt -x 1433 -y 955 Big.hdr > resize.hdr 4.Crop & cleaning mask ra_xyze -r -o -u resize.hdr | pcompos -x 800 -y 800 - -315 -78 > crop.hdr | pcomb -s -1000 output_masked2.hdr 5. Evalglare analysis echo "VIEW= -vta -vh 180 -vv 180 -vp 0 0 0 -vd 1 0 0 -vu 0 0 1" > output_masked2.hdr evalglare output_masked2.hdr The problem is that Evalglare reports errors after the crop process. error: no valid view specified (There was no evalglare errors when I test it with the resized image.) I has checked the luminance values of the HDR in photosphere and it looks OK! Do I need to use another crop command for evalglare processing? Please, let me know if you have any ideas.
