Photomosaic (FINAL)

original image


















I divided my "big picture" into 40 tiles, 15x15 pixels each,and then assigned them according to the big picture's average colour(Jen's method).
I had difficulties running the program because function "increase" did not increase matris exactly to 600x600, although I checked the size of this matrix previously, and it was correct.I used the following function to check the average colour of my big picture:

function[B]= average(X)
B=sum(sum(X))/(size(X,1)*size(X,2));
end

This is the final code for my photomosaic:
