Failure to use adaptiveThreshold: CV_8UC1 in function adaptiveThreshold

Question

I have used openCV python and encountered an error.

img_blur = cv2.medianBlur(self.cropped_img,5)
img_thresh_Gaussian = cv2.adaptiveThreshold(img_blur, 255,          


        

Answer 1

you have to imread your image in grayscale, so use the code below:

image = imread('address', 0)

0 exchange the channel of image to grayscale
