How to convert image to csv

#1

hello sir i prepared the final image but i am not able to convert it to csv file its showing error in the way u converted a 2D structure into csv

Hey @gaurangagarwal557, lets suppose ‘ans’ is the variable having final image as answer. You can follow like this,
ans = ans.reshape((-1,3))

and after that you can simply convert it into csv.
import pandas as pd
pd.DataFrame(ans).to_csv(“solution.csv”, header = [‘r’,‘g’,‘b’], index = False)

Hope this resolved your doubt. :blush:

yes it worked thank you very much
sir can u explain why reshape(-1,3) i mean what did -1 did.

#4

Hey @gaurangagarwal557, so this is the feature of numpy i can specify one shape parameter as -1, which means its value will be calculated automatically. Initially ans.shape (height, width, 3) and after i reshaped it, i can do it either way 1. ans.reshape( height*width , 3) or ans.reshape(-1,3) both are equivalent.

Hope this resolved your doubt. :blush:
