What is interpolation in C?

Interpolation search is an improved variant of binary search. This search algorithm works on the probing position of the required value. For this algorithm to work properly, the data collection should be in sorted and equally distributed form. It's runtime complexity is log2(log2 n).

What is the difference between bilinear and bicubic interpolation?

In contrast to bilinear interpolation, which only takes 4 pixels (2×2) into account, bicubic interpolation considers 16 pixels (4×4). Images resampled with bicubic interpolation can have different interpolation artifacts, depending on the b and c values chosen.

What is bilinear upsampling?

What do we mean by bilinear upsampling? Let's start with the most simple explanation, without the nitty gritty: it is creating a larger resolution image where every sample is created from bilinear filtering of a smaller resolution image.
