2019-02-14 06:52:52 -0600	edited answer	How to incorporate white into color system? 2 steps are required: Split the image into 3 planes: h, s, v. Create the histogram of h-plane. Filter out color
2019-02-11 10:29:40 -0600	commented question	Hue thresholding This is better, but still mask is an array.
2019-02-11 09:39:30 -0600	commented question	Hue thresholding inRange should work too, only it requires more arrays so consumes more memory. This may be a problem for large images.
2019-02-11 09:34:11 -0600	commented answer	Hue thresholding Classical bug. Did you ever use de-bug-ger? :) If it is about threshold in general, not python-specific - come on, ask.

2019-01-30 12:49:50 -0600	commented answer	How to incorporate white into color system? I agree. That is, for complete color detection we need to take into account all components, not only hue. I formulate th

2019-01-30 09:46:53 -0600	marked best answer	How to incorporate white into color system? P.S. An important update to answer 2. In comparison to RGB, HSV is convenient because it keeps color in the separate channel. One problem. It does not include black and white. I don't need intensity of color(that is value), but humans do recognize black and white as separate colors. White is absent.

2018-12-20 13:28:14 -0600	commented answer	How to determine the angle of rotation? Sounds good. Thanks.
2018-12-20 13:27:18 -0600	marked best answer	How to determine the angle of rotation? There is a square in an image with equal sides (that is inside another square). Does OpenCV have functions which can help to efficiently calculate the angle?
