The following piece of code is given for recognizing hand$-$written digits. You are required to

fill in the box which includes $"?"$ as given below so that you find moments based on the set of

input images. Then, the moments will be classified thanks to the piece of code which follows

the box.

and i dont want you to cheng any thing in the given Q you can cheng in this cod that i well send and Merge codes solve it wath this methoed

$1.$ Moments

Image moments help you to calculate some features like center of mass of the object, area of the object etc. Check out the wikipedia page on Image Moments

The function cv$.$moments$()$ gives a dictionary of all moment values calculated. See below:

import numpy as np

import cv$2$ as cv

img $=$ cv$.$imread$(\text{'}$star$.$jpg$\text{'},$ cv$.$IMREAD$\_$GRAYSCALE$)$

assert img is not None, "file could not be read, check with os$.$path.exists$()"$

ret,thresh $=$ cv$.$threshold$($img$,127,255,0)$

im$2,$contours,hierarchy $=$ cv$.$findContours$($thresh$,1,2)$

cnt $=$ contours$[0]$

M $=$ cv$.$moments$($cnt$)$

print$($ M $)$

From this moments, you can extract useful data like area, centroid etc. Centroid is given by the relations, Cx$=$M$10$M$00$ and Cy$=$M$01$M$00.$ This can be done as follows:

cx $=$ int$($M$[\text{'}$m$10\text{'}]/$M$[\text{'}$m$00\text{'}])$

cy $=$ int$($M$[\text{'}$m$01\text{'}]/$M$[\text{'}$m$00\text{'}])$
