From the reviews:
"The book presents a detailed review of the cutting-edge approaches in visual indexing and visual information retrieval. It provides recipes for a practitioner who is keen to implement these techniques. ... The book also carefully develops a way of building a multi-scale graph, based on the multisolution approach, to fasten the speed of the request." (Jean Th. Lapresté, Zentralblatt MATH, Vol. 1257, 2013)
