LLTV:Local Linear Total Variation Filter
Qiu Tian-shuang · Dianzi xuebao · 2012
This paper proposes a novel edge-preserving smoothing filter-local linear total variation filter(LLTV),used to perform effective image filtering.Based on a local linear model and combining total variation regularization,this method can filter out noise while preserving edges and fine-scale details.The experimental results show that LLTV filter is effective in a great variety of computer vision applications including noise reduction,detail smoothing/enhancement and HDR compression.
