Fabric image retrieval method of locally invariant texture feature based on geometrical shape

Abstract

The invention discloses a fabric image retrieval method of a locally invariant texture feature based on a geometrical shape, comprising the following steps: 1, offline generating an index structure ofa fabric image database; 2, forming a user query: extracting a locally invariant texture feature based on the geometrical shape of a sample fabric image input via the user, and forming a query that the index database can be retrieved, wherein the step of extracting the locally invariant texture feature based on the geometrical shape is implemented according to the following steps: (1) conversionto a grayscale texture; (2) topographic map expression of the fabric image; (3) feature extraction: one is local expression of the image texture feature, the second one is an expression of structuralrelationship between nodes, and the third one is using a shape contrast feature to remove the influence of local contrast on features; (4) statistical expression of features; 3, calculating similarity, and outputting the result. The fabric image retrieval method provided by the invention proposes a locally invariant texture feature based on the geometrical shape, and the fabric image can be effectively retrieved by using the feature.

Description

technical field [0001] The invention relates to the field of computer multimedia information retrieval, in particular to a fabric image retrieval method based on local invariant texture features of geometric shapes. Background technique [0002] Textile and clothing are one of the most basic needs for human survival. my country is a major textile production and export country, and it is also the world's largest clothing consumer and producer. The textile industry is a traditional pillar industry of my country's national economy, an important livelihood industry and an industry with obvious international competitive advantages. With the rapid development of the textile industry, fabrics and other products as the main textile products are showing a continuous growth trend. The ensuing problem is how to use computers to organize, manage and effectively search the increasing fabrics. Especially important for fabric dealers, clothing industry, etc. For the clothing industry, fa...
