Saving images for web/email/other media with the best compression ratio and quality is a difficult task if you don’t have the right tools. Choosing the right format then choosing the right parameters are the key factors of smaller files.
Waifu2x Caffe rewrites only the conversion function of the image conversion software "waifu2x" using Caffe and is software developed for Windows. Although it can convert with CPU, using CUDA (or cuDNN) can convert faster than CPU.
Gigapixel AI helps you do a single thing very well: increase image resolution in a natural way. This is pretty hard to do. Most upscaling algorithms don’t know how to accurately fill in missing pixels, so you end up with blocky low-quality results.
