求翻译:Nearzero,fðÞ is preferable to have aquadratic behavior and satisfy fð0Þ ¼ 0,so that uiðxÞ can be better smoothed in homogeneous regions.Then necessarily f should have a nonconvex shape.In our model,we set fðsÞ ¼ s2=ð1þs2Þ. Obviously,the convex TV(fðsÞ ¼ jsj) does not satisfy the growth condition because lims-þ1jsj ¼ þ是什么意思?![]() ![]() Nearzero,fðÞ is preferable to have aquadratic behavior and satisfy fð0Þ ¼ 0,so that uiðxÞ can be better smoothed in homogeneous regions.Then necessarily f should have a nonconvex shape.In our model,we set fðsÞ ¼ s2=ð1þs2Þ.
