cv::threshold otsu value Hello, in Python I can read the otsu threshold value like this otsu_thr, otsu_mask = cv2.thres

with math, yes. but is there easier way/algorithm built-in? :D

okey, I fixed, now says they are triangle all. after this point?, directions :)

okey, I fixed, now says they are triangle all. after this point?

no way, algorithm says those are rectangle, even tried blurring :(

approxPolyDP says it is rectangle. now trying to fix it

then? how can I get direction/orientation of a triangle?

Hello, I wanted to read characters/triangles from a bar. I applied Otsu with different values to this bar but couldn't get the all characters exactly. The characters' colours are varying. Could someone give another way/algorithm to extract them? Also, is there any way to color sweeping, I mean try all colours then if exist, extract (extract all colored from black&white backgrounded image) ? Thanks for help

ret,im1 = cv2.threshold(crop_img,0,255,cv2.THRESH_OTSU)

The challenges, the last one is the hardest :(

The best one I got which is unsuccesful:
