# Reading the image from the present directory
image = cv2.imread("image.jpg")
# Resizing the image for compatibility
image = cv2.resize(image, (500, 600))
 
# The initial processing of the image
# image = cv2.medianBlur(image, 3)
image_bw = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
 
# The declaration of CLAHE
# clipLimit -> Threshold for contrast limiting
clahe = cv2.createCLAHE(clipLimit = 5)
final_img = clahe.apply(image_bw) + 30
 
# Ordinary thresholding the same image
_, ordinary_img = cv2.threshold(image_bw, 155, 255, cv2.THRESH_BINARY)
 
# Showing all the three images
cv2.imshow("ordinary threshold", ordinary_img)
cv2.imshow("CLAHE image", final_img)
