CPU Downscaling #19

Closed dcharatan closed 4 years ago

dcharatan commented 4 years ago

Implemented CPU downscaling. I modified the downscaling and added the following tests:

TestDownscaler: Runs simple tests with a series of 4x4 int-based images. TestDownscalerWithImage: Downscales the test_cit image in the folder of examples and confirms that the average value stays the same after downscaling.

Note: Both tests are templated so that they can be used with any implementation of Downscaler.

The tests compiled and ran successfully on my PC.

I'm sure there's an xkcd joke about the overuse of templates but lets ignore that :p.

I compared the result with scipy's bilinear downscale scipy.misc.imresize(img, size, interp='bilinear', mode=None) and below is their SSIM:

png_test

3_ssim

I think the diff. is small enough to ignore.
