Bilinear interpolation on images stored as Python Numpy ndarray
If you are working in image processing and using Python as a prototyping script language to test algorithms, you might have noticed that all the libs providing fast image interpolation methods (to either sub-sample or over-sample) work in 8 bits unsigned integers ([crayon-5ffdc72df30bc404569909-i/]). This is quite annoying if you are working with floating point images. [...]
