Description
The problem I encountered was that I used tif images with a size of 1g, using cv2.imshow, it showed an error, when I used small images, there was no such error
code
import os
os.environ["OPENCV_IO_MAX_IMAGE_PIXELS"] = pow(2, 40).__str__()
import numpy
import cv2
img = cv2.imread('G04002.tif', 1)
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) # siva slika
cv2.imshow('gray', gray)
vis = img.copy()
ret, thresh = cv2.threshold(gray, 0, 255, cv2.THRESH_BINARY + cv2.THRESH_OTSU)
cv2.imshow('thresh', thresh)
mser = cv2.MSER_create()
#mser = cv2.MSER_create(_min_area=2, _max_area=1000)
regions = mser.detectRegions(thresh)
hulls = [cv2.convexHull(p.reshape(-1, 1, 2)) for p in regions[0]]
cv2.polylines(vis, hulls, 1, (0, 255, 0))
cv2.imshow('mser', vis)
cv2.waitKey(0)
