Embodiment Construction

[0015] Those of ordinary skill in the art will appreciate that the following detailed description of the exemplary embodiments is illustrative only and is not intended to be limiting in any way. Other embodiments will readily appear to such skilled persons having the benefit of this disclosure. Reference will now be made in detail to implementations of the exemplary embodiments as illustrated in the several drawings. The same reference numerals will be used throughout the drawings and in the following detailed description to designate the same or like parts.

[0016] The invention proposes a method for improving the results returned by an image search engine according to image content. The keyword to be retrieved entered by the user is used as a semantic category, the positive and negative samples corresponding to the semantics to be retrieved are selected from the image collection returned by the image search engine, and a classifier that distinguishes relevant and irrelevan...

Abstract

The invention provides a web image search method. The method provided by the invention comprises the following steps of: carrying out an image search by a user through utilizing keywords, wherein the keywords are semanteme to be searched of the image; in a searched image set, judging and studying to obtain a classifier corresponding to the semanteme to be searched; utilizing the classifier to calculate the correlation degree between each image and the semanteme to be searched; and sequencing the image set according to the correlation degree and returning the sequenced image set back to the user. The experimental result shows that the method provided by the invention can effectively improve the image search result based on the text.

Description

technical field [0001] The invention relates to a web retrieval, in particular to a web image search engine and its realization method. Background technique [0002] With the development of network technology and image processing technology, a large number of digital images have been accumulated on the Internet, and the number is still growing at a high speed. For example, the online photo sharing website www.flickr.com has only been in operation for 4 years, and has reached 40 million visits per month, and a total of 2 billion pictures have been uploaded, with an average of several million pictures uploaded every day. People urgently need to use effective automatic image retrieval technology to help them quickly and accurately obtain the required information from the huge, real-time expanding and changing network image database. [0003] Existing image retrieval methods can be divided into two categories: Text Based Image Retrieval (TBIR) and Content Based Image Retrieval ...
