Pattern retrieval algorithm based on Sift feature
Hongzhi Zhang · Tianjin Gongye Daxue xuebao · 2010
The way to search for the same draft based on Sift feature is proposed.By use of DoG,Sift consists of adjacent scale Gaussian differential unclear and input image convolution,the calculation of scale space is simplified.It has a good ability to identify the similar image or sub-image,it will save a lot time,so that we can use the source of draft best,avoiding doing the same draft and wasting time.In addition,the method is significantly used to identify clothing original design of plate-type pattern.
