Astronomy Python - Mars Planet Surface - Creating Sharpen Image from Blur Image

  In Astronomy, sometimes the images send by satellite/telescope could be Blur and one would be interested to make the image Sharpe.

The Kernel (it is matrix representation) is to process the image -from Blur image to Sharpe Image.

Convolution Matrix, Mask, Matrix/Array are the other names given to the Kernel.

                          Below is the example of Mars Surface Blur Image

Below is the processed image which has now become Sharpe Image 

Please  open both images to see the effect.7Below is the python code used.

******************************************************************

# load the required packages

import cv2

import numpy as np

# load the image into system memory

image = cv2.imread('E:\\astronomy_related\\blurr_to_clear_image\\marssurface_blurr.jpg', flags=cv2.IMREAD_COLOR)

# display the blurr image to the screen

cv2.imshow('Mars Surface blurr', image)

cv2.waitKey()

cv2.destroyAllWindows()

# display the sharpen image based on below kernel

kernel = np.array([[0, -1, 0],

                   [-1, 5,-1],

                   [0, -1, 0]])

image_sharp = cv2.filter2D(src=image, ddepth=-1, kernel=kernel)

cv2.imshow('Mars Surface Sharpened', image_sharp)

cv2.waitKey()

cv2.destroyAllWindows()
