Question
Convert the gray scale image to a binary image by setting all the array elementsabove 55 to 1 and below 55 to 0 (zero).
Solution
Sure, here is a step-by-step guide on how to convert a grayscale image to a binary image using Python:
- Import the necessary libraries:
import cv2
import numpy as np
- Load the grayscale image:
img = cv2.imread('image.png', cv2.IMREAD_GRAYSCALE)
- Set a threshold value:
threshold = 55
- Apply the threshold to the image:
_, binary_img = cv2.threshold(img, threshold, 1, cv2.THRESH_BINARY)
In the above line, cv2.threshold is a function that is used to apply the thresholding. The first argument is the source image, which should be a

The above figure shows a digital picture represented as a nested list. Each element in the list stores the value of a single pixel. Each pixel is either black or white. A white pixel is represented by 1 and a black pixel by 0.Write a Python function grey_value(image) which takes an image image (represented as a list of lists like above) and returns its grey value. The grey value of a black and white picture is defined as the number of white pixels divided by the total number of pixels in the picture. Your function should return the grey value as a single floating-point number in the range 0.0 to 1.0.
