Assignment 7, Q1-method 2

I am having difficulty getting method 1 to work properly but have completed this question using method 2. Please see a copy of my octave command and resulting images.

Please note that I created a "shrinkimg function" in octave and used it repeatedly to shrink my images by factors of 0.75, 0.25 and 0.1. Please click on the octave for more details as I have included # comments # to my code.



To use the function again you simply have to:

1) load your image - octave>A=imread("imagename.jpg");
2) apply shrink function - octave>B=shrinkimg(A, f); # f=0.75, 0.25, 0.1...
3) double your B - octave> C=double(B)/255;
4) then imwrite your new image C...

Here are my new images following the shrink function applied to my first picture.
