Using python opencv, easily possible to crop image. Four parameters are necessary for cropping image.

1. start index or pixel along x axis (start_x_axis)
2. width or cropping value along x axis (cropping width)
3. start index or pixel along y axis (start_y_axis)
4. height or cropping value along y axis (cropping height)

Code:

First install python opencv using pip install opencv-python

# importing opencv
import cv2

# cropping width
c_width = 500

#cropping height
c_height = 600

# read image
# input = cv2.imread(path)
input = cv2.imread("image.jpeg")


# real width of image
w = input.shape[1]

# real height of image
h = input.shape[0]


# your required value, input here what you want
start_x = 0


# your required value, input here what you want
start_y = 0


# crop image
crop = input[start_y : start_y + c_height, start_x : start_x + c_width]


# save image

# cv2.imwrite(output_path, crop) 
cv2.imwrite("output.png", crop)

Input:

image.jpeg ( in same folder in python file)

Output:
