An AI Colorize tool automatically adds realistic color to black and white photos. By training on vast datasets of colored images, these AI models can intelligently predict the appropriate colors for different objects and scenes, from skin tones and clothing to landscapes and cityscapes. This technology is a powerful way to bring old family photos and historical images to life, adding a new layer of depth and realism. It's a fascinating application of deep learning that makes photo restoration more accessible than ever before.
