i want learn image processing. made program. compared 2 images using emgucv. ı want meausere pixel width , height. how can ı ?

i read there no example emgucv. have no professional camera. use web cam present. , ı use coin measure pixel width , height. problem ı don't know how it.

please me.

thanks.

to obtain factor mm/pixel have capture image of object of known size. object must reside within plane want measurements. normal setup plane parallel camera sensor.

then count number of pixels along known dimension of object. divide metric dimension number of pixels.

once have factor can use measure dimension withn plane counting number of pixels , multiply factor.

this approach sufficient layman's tasks.
