Problem Set 2

Assigned: February 23, 2007 (Friday)
Due: March 6, 2007 (Tuesday)
What to Return: Email your m-file(s) to the TA by midnight.

Problem: 

Under the Matlab image processing toolbox, there is an image called "pears.png". 

Your task is to write m-file(s) that will do the following:

1) Find the locations of visible pears.
2) Determine the relative sizes of each pear. (that is, number of pixels belonging to each pear)


Write a function:

function [ pear_x, pear_y, pear_size ] = ps2(img);

% img: input image (could be color image)
% pear_x: a column vector keeping the x coordinates of pears
% pear_y: a column vector keeping the y coordinates of pears
% pear_size: a column vector keeping the size of the pears


Evaluation: It is not easy that an algorithm finds all pears and sizes accurately. 
Your grade will be based on the relative performances.
