基于草图的图像检索技术

Image Retrieval based on Hand-drawn Sketches

基于草图的图像检索可以帮助用户利用手工勾勒的草图来表达自己的检索意图,相比关键词检索,能更直观地表达检索意图,通过图形特征匹配完成图像检索,是一种有效的基于内容的图像检索方式。笔者介绍草图输入、预处理、特征表示、特征匹配、图像反馈等基于草图的检索系统模块,并从人机交互、特征优化、检索提速、检索结果评估等方面介绍了检索系统研究和应用的发展方向。

Sketch based image retrieval can help users to express their retrieval intention by hand sketch,which can be more intuitive to express retrieval intention through graphical feature matching compared to keyword search.Image retrieval is an effective retrieval method of content based image.The author introduces sketches input,preprocessing,feature representation,feature matching and feedback module,which are included in image retrieval system.And then the author introduces the development direction of the research and application of retrieval system including human-computer interaction,feature optimization,search speed,search result evaluation.
