Sharpening Method using TV Regularization for Black-out Images
Takuya Nakashima, Tomio Goto · 2020 IEEE 2nd Global Conference on Life Sciences and Technologies (LifeTech) · 2020
We propose an algorithm that can obtain clear and sharp images without losing the characteristics for blackout images. It utilizes Total Variation regularization, and uses gamma correction for cartoon components and Pulse Enhancement Filter for texture components. The experimental results show that it can obtain clear and sharp images. Our proposed method can be used for life science technology such as security camera and face authentication system.
