I have some problems in understanding imresize() fnc.
1. What is differences between 'interpolation method' and 'interpolation kernel'?
2. I want to resize an image (for Ex. A=[1 2 125;0 8 5;4 3 100; 1 4 5]) into 3*2 image matrix by using cubic interpolation method. How does the imresize() do it? is there a simple matlab code or algorithm to understand it?
For kernel in image processing see:
http://en.wikipedia.org/wiki/Kernel_%28image_processing%29
Code to your problem:
A=[1 2 125;0 8 5;4 3 100; 1 4 5];
image(A)
B = imresize(A,[3 2],'cubic');
figure
image(B)
For algorithm type in MATLAB:
open imresize
Dear Knor
thank you for reply.
I opened the imresize() fnc. and read it line by line. but i don't know that what are the 'weight' and 'indices' variables? for the matrix given above can you help me to calculate its resized matrix step by step,here? Thanks
