Video Beauty Master! Blurry Faces Turn into HD in Seconds! KEEP Technology Lets You Say Goodbye to Pixelated Faces

KEEP technology is an innovative video super-resolution method specifically designed to enhance the clarity of faces and the vividness of expressions in videos. It employs a 'feature propagation based on Kalman filtering' framework to significantly improve video quality by maintaining consistency in facial features, especially effective in blurry or degraded videos. Key technologies include an efficient VQGAN generation model, Kalman filtering networks to promote temporal information propagation, and a cross-frame attention mechanism to enhance temporal consistency. This makes KEEP technology effective in restoring facial details and avoiding blurriness distortions.
