Sharpness parameter?

If I understand principle of Helicon Focus operation correctly, method to determine what detail of stack image is in focus based on sharpness of this detail: if sharpness of detail higher than some threshold, it means that it is in focus, so it should be related to stack distance of this image. If t...

Re: Calibrated depth map?

Catherine, Thanks for your reply. >The min value corresponds to the first image of the stack, the max value - to the last one. Is this statement correct, if in stack a few first and a few last frames are out of focus? Perhaps, is more correctly to assign to depth step between frames value (B-А)/255?...

Re: Calibrated depth map?

Catherine,

Thanks a lot for your valuable information. It is very important, it seems it should be placed somewhere in Helicon Focus manual, tutorial.

Please, could you inform, is it possible to calibrate depth data, extracted from vertices of *.obj file?

Best regards

Valeriy

Calibrated depth map?

Hello I'm using microscope with stepmotor on focus knob. So, I know the distance between stack images along optical axis of microscope, stack step. After processing by Helicon Focus I can obtain depth map. Depth values are distributed between 0 and 255. Is it possible to establish relationship betwe...
