Embodiment Construction

[0013] The content-based picture search method and its parallel optimization method of the present invention will be introduced in detail below in conjunction with the accompanying drawings. The whole picture search process of the present invention is divided into: back-end processing and front-end query process, such as figure 1 shown. The original image gets an indexed query database through feature extraction, dimensionality reduction and indexing. The user inputs a picture containing the content they want to query, the system extracts the features of the query picture to obtain the feature vector, and then uses the same method as the back-end picture processing to perform dimensionality reduction, and uses the reduced dimensionality vector to the index database to find the best match Several pictures in the database are sorted by similarity, and finally the system presents the sorted pictures to the user to complete a query process.

[0014] Feature extraction is a metho...

Abstract

The invention discloses a picture searching method based on content and a parallel optimization technique and relates to an internet picture search engine technique, which aims to accurately and rapidly search pictures which are similar to the content of a picture submitted by a user. The user searches pictures according to a picture, submits a picture to be queried, and a picture search system returns e pictures which are similar to the picture visually to the user. The picture searching method disclosed by the invention comprises two parts: front end query and rear end processing, wherein a front end comprises a user input interface and a result return interface; the rear end comprises characteristic extraction, similarity computation, characteristic vectors dimension reduction and indexing. By developing the parallelism of the search system, the performance of the whole picture search system is optimized on the aspects of serial and parallel, thereby enhancing the corresponding speed of query.

Description

technical field [0001] The invention relates to an Internet picture search engine and a parallel optimization technology, in particular to an efficient picture search method based on the content of the picture itself. Background technique [0002] With the popularization of large-capacity storage and digital image equipment (video cameras, cameras), a large number of different types of pictures will be produced every day, such as science, medicine, geography, life and so on. How to effectively retrieve these massive pictures, and then facilitate people to effectively browse, search, and manage the pictures they are interested in, is a problem that needs to be solved urgently. [0003] Currently commercial image search engines include Google Image Search and Baidu Image Search. These later search systems are based on keywords and image tags. Keyword-based image and video retrieval has its inherent shortcomings. The content in the picture is rich, and it is difficult to exp...
