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 should load your file like this

src.create(rows, cols, CV_8UC1);
src = imread(your-file, CV_8UC1);

and after that

adaptiveThreshold(src, dst, 255, ADAPTIVE_THRESH_GAUSSIAN_C, THRESH_BINARY, 75, 10);
