Both deconvolution and the different resize-convolution approaches are linear operations, and can be interpreted as matrices. - This a helpful way to see the differences between them. + This is a helpful way to see the differences between them. Where deconvolution has a unique entry for each output window, resize-convolution is implicitly weight-tying in a way that discourages high frequency artifacts.
We've had our best results with nearest-neighbor interpolation, and had difficulty making bilinear resize work.
