Topaz A.I. Gigapixel 4.4

Gigapixel AI from Topaz lets you upscale videos using multiple frames of information to recover detail with no temporal artifacts.

The tool features automatic face refinement to offer you powerful and accurate face enlargement. Face Refinement will detect very small faces (16×16 px to 64×64 px) and apply targeted, improved upsampling through machine learning. Ordinarily, faces this small in dimension can be very difficult to upscale, leaving them vulnerable to unpredictable results during enlargement. With this improvement, Gigapixel AI produces a more seamless enlargement of faces within your photos, so you’ll be satisfied with more natural-looking results.
