Problems solved by technology

The first problem is because text search engines rely on the text descriptions of relevant pages. If the page only has the words "car" and no "red", the images of cars will be missed, even though they are also red.
The second problem is that although the user specifies the search feature "red", this information is not used in the image search process based on image content, so this information is wasted

Embodiment 1

[0047] A flow chart of the embodiment of the present invention is shown in Figure 2, and the search method for comprehensively utilizing image and text information is carried out in the following steps:

[0048] 1. Send the pictures taken by the terminal and the text input by the text input module to the server through the wireless communication link.

[0049] 2. The input image is compared with other images that have been processed. If it is confirmed that it is a repeated image, the result of this recognition can be obtained based on the previous recognition results; if not, proceed to the following steps.

[0050] 3. Analyze the text instructions entered by the user. The result of the analysis includes at least two parts of keywords, one part is restrictive keywords to limit the scope of search objects, and the other part is descriptive keywords to describe Search for external features of an object. Parsing can be implemented in many ways. The simplest example is to use no...

Embodiment 2

[0072] A flow chart of the embodiment of the present invention is shown in Figure 3, and the search method for comprehensively utilizing image and text information is carried out in the following steps:

[0073] 1. Extract the feature vector from the picture taken by the terminal, analyze and extract the feature vector from the text instruction input by the user, and the result of the analysis includes at least two parts of keywords, one of which is a restrictive keyword, which is used to limit the scope of the search object, The other part is descriptive keywords, which are used to describe the external characteristics of the search object;

[0074] 2. The image and text feature vectors extracted in step 1 and the limited keywords, descriptive keywords and their weights obtained by analyzing the text instructions input by the user are sent to the server through the wireless communication link;

[0075] 3. Search images in a text-based image search engine using qualified keywo...

Abstract

This invention relates to index system and method, which comprises terminal, servo, word input module, image analysis engineer, word order analysis module, index engineer and wireless communication linkage, wherein, inputting captured pictures and words through wireless communication linkage to servo for analyzing word order; using key word to index images based on words and analyzing input image content to get characteristic vector; processing index based on image content combined with characteristic vector and description key words to generate user index result.

Description

technical field [0001] The invention relates to a search system and a search method, in particular to a search system and a search method which comprehensively utilize image and text information. Background technique [0002] It is a new type of search method to search the content of the remote server through a mobile terminal, such as a mobile phone or a palmtop computer. According to different ways of inputting queries, there are three ways to search for existing moving images. The most common mobile search is a text search. In this method, the images in the database are marked with words manually or automatically, and the search is performed by matching the words. But in many cases, it is difficult to describe the search object with only words. In mobile phone applications, it is also inconvenient to input a large amount of text. [0003] Another approach to mobile search is to use an image search interface. The method of automatic image recognition can facilitate th...
