[Invited Talk] Image smoothing based on L0 gradient regularization and its applications
Ryo Matsuoka (Univ. of Kitakyushu) SIP2020-37
Abstract (in Japanese) (See Japanese page) 
(in English) This talk outlines research on image processing based on L0 gradient regularization that promotes sparseness in the gradient domain. A piecewise smooth image is obtained by minimizing the L0 gradient together with the commonly used data-fidelity term based on the L2-norm. It is useful for some applications such as image smoothing, contrast enhancement, and tone-mapping, and so on. It is also used for image restoration such as blur removal and JPEG noise removal for illustration images. In this talk, the previous studies on L0 gradient regularization are briefly reviewed. In addition, our researches on L0 gradient regularization are explained.
