Description
1. Use image called mask in file chars45.mat to study shape analysis using Hu’s moments
for the characters:
A,B,C,D,E,F,G,H,I,K,L,M,N,O,R,S,T,U,V,Y
a,c,d,e,f,g,h,i,k,l,m,n,o,p,r,s,t,u,v,y
0,1,2,3,4,5,6,7,8,9
Use a character from the image as a model, (A1,(A2,(A3,(A4,(A5,(A6), for each character above. Develop the functions listed below and report performance in terms of overall
and per character success.
function Mpq = CS4640_central_moment(pts,p,q)
% CS4640_central_moment – compute a central moment
% Mpq = sum sum (xˆp*yˆq)
% x y
% On input:
% pts (nx2 array): row and cols of points
% p (int): exponent for x
% q (int): exponent for y
% On output:
% Mpq (float): Mpq moment
% Call:
% M00 = CS4640_central_moments([1 1; 2 2; 3 3],0,0);
