What is RGB threshold?

Thresholding is an operation often used to generate black and white images. For this function we'll also use it to rescale the image so that all of the final values fall in the range 0 to 255. (Although in this case, the output pixels will ONLY be 0 or 255.)

What is cv2 threshold?

We use the cv2. THRESH_BINARY_INV method, which indicates that pixel values p less than T are set to the output value (the third argument). The cv2. threshold function then returns a tuple of 2 values: the first, T, is the threshold value.

What is cv2 adaptive threshold?

adaptiveThreshold is the threshold method, again just like the simple thresholding and Otsu thresholding methods. Here we pass in a value of cv2. THRESH_BINARY_INV to indicate that any pixel value that passes the threshold test will have an output value of 0 . Otherwise, it will have a value of 255 .
