Bilinear interpolation - point outside of the grid
Suppose I have a 10x10 pixel grid. Assume that each pixel has value 1 (it is not important). Now in the typical case, if I would like to sample a point inside of the grid, for example p1=(0.5,0.5)=(x,...

Using PyTorch grid_sample to reconstruct left image from right image and inverse depth
I'm implementing the basic architecture from this paper: https://arxiv.org/pdf/1705.08260.pdf in PyTorch.
It consists of an autoencoder and Spatial Transformer. Output of the autoencoder is fed into t...

How to resample a 2-D spatial matrix (not a time series) using a weighted average to from the 1km grid to the 0.25 degree
I have a bumpy matrix A with shape [num_X, num_Y]. The corresponding lattitude and longitude array is A_lat (of size [num_Y,1]) and A_lon (of size [num_X,1]). And the each element of this matrix for e...

How do I get the complexity of bilinear/nearest neighbour interpolation algorithm? (calculate the big O)
I want to calculate the big O of the following algorithms for resizing binary images:
Bilinear interpolation:
double scale_x = (double)new_height/(height-1);
double scale_y = (double)new_width...
