question regarding the resize function of OpenCV
Does resize function of Opencv first filters the high spatial frequency before downsizing to prevent image-aliasing?

Depending on the interpolation method chosen, there are different results. The default linear interpolation reduces aliasing more than INTER_NEAREST, but not as much as the others. For downsampling it's difficult to see much difference between anything other than Nearest.
