RGB values for params of inRange #3

Open sid2364 opened 7 years ago

sid2364 commented 7 years ago

I don't really understand what's going into inRange from this:-

# Filter by colour
# 0-10 hue
#minimum red amount, max red amount
min_red = np.array([0, 30, 30])
max_red = np.array([10, 100, 100])
#layer
mask1 = cv2.inRange(image_blur_hsv, min_red, max_red)

#birghtness of a color is hue
# 170-180 hue
min_red2 = np.array([170, 30, 30])
max_red2 = np.array([180, 100, 100])
mask2 = cv2.inRange(image_blur_hsv, min_red2, max_red2)

I couldn't really understand from the docs.

What exactly is going in?

@sid2364 I think this link will clear your doubts: [http://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_imgproc/py_colorspaces/py_colorspaces.html]
