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 Image Credit: NASA/JPL-Caltech Below is the processed image which has now become Sharpe Image Please open both images to see the effect.7 Below 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...

Nebra Sky Disk is made up of Bronze, it is 30 centimeter wide. Important figures on the disk- 1)Sun or Full Moon (full circle) 2)Crescent Moon (crescent circle) 3)Pleiades Constellation (group of 7 stars - small circles) 4)Other stars (other small circles) 5)2 Golden arcs (at the border of disk) -Angle between Solstices (currently 1 seems to be missing at opposite side) 6)1 Golden arc (thin shape)- Is not yet fully known Credit-By Dbachmann, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=1500795 This disk was found in Mittelberg forest in germany and the disk is though to be from period 1600 - 1560 BCE Activity for School kids- Draw the above disk on card board.
