Re: question in use img.findcircle() to find the iris

Yeah, the find_features() method can find the eyes sometimes, actually the find_circle method can find the cr(the white spot reflect by the irlight),but can't find iris,just show like this http://chuantu.biz/t6/353/1533357813x-1566688706.jpg , i set the findcircle() r_max parameter bigger,and the ci...

I used data from GTSRB(http://benchmark.ini.rub.de/?section=gtsrb&subsection=dataset) and after using openCV and (https://github.com/openmv/openmv/blob/m ... cascade.py) script I have get the trafficsign-recogniti...
