1 (Worst) Gigapixel AI creates beautiful photo enlargements using machine learning. Breathtakingly sharp prints. High-resolution cropping in post-production. iPhone photos that look like they came out of a DSLR. No matter why you’re enlarging your photos, you always want the best possible quality for your results. Gigapixel AI is currently the only photo enlargement product available that can actually add detail back to your upscaled photo. Automatic face refinement With our latest developments in machine learning and image recognition, we’ve implemented automatic face refinement in Gigapixel AI to offer you more powerful and accurate face enlargement. You’ll see a toggle in the right panel to enable/disable the new Face Refinement feature. Face Refinement will detect very small faces (16×16 px to 64×64 px) and apply targeted, improved upsampling through machine learning.
