Greeting experts,
I need your opinion on the following statements. In order to get the window for linear interpolation, I had the formula: p(t)=1-t/Ts where Ts, I took it as 5 since I sub sampled the original image 4 times. Then, I had my window from -Ts to +Ts i.e., [0 1/5 2/5 3/5 4/5 1 4/5 3/5 2/5 1/5 0] and hence this is my frame. My question is that I want to know this is it for showing FIR filter in relation to linear interpolation.
My second question, how would we relate FIR filter to bi-cubic interpolation on image? I searched a lot on net, but most of information are either too technical or not related to images at all. Also I want to understand the code for its implementation.
I would be everly grateful for any kind of help received over here.
