Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0038] The invention provides a fast matching retrieval method for cloth images. The method first extracts the SIFT features of the images, then performs K-Means clustering on the SIFT feature vectors of all images to generate a bag of visual words, and calculates the shape feature histogram of each image. Finally, the E2LSH algorithm is used to realize the automatic and fast matching and retrieval of images.

[0039] 1.SIFT feature extraction

[0040] The implementation of SIFT algorithm is divided into two steps: feature point detection and feature descriptor.

Abstract

The invention relates to a method for rapidly matching and retrieving cloth images. The method comprises steps of firstly extracting SIFT characteristics of images; then, carrying out K-means clustering on the SIFT characteristics of the images so as to generate vision word bags and calculate a shape characteristic histogram of each image; and finally, using the E2LSH algorithm to achieve automatic and rapid matching and retrieving of the images. Compared with the prior art, the provided method is characterized in that the same cloth and similar cloth can be quickly found and is advantaged by high matching precision and rapid retrieving speed.

Description

technical field [0001] The invention relates to a cloth retrieval method, in particular to a cloth image fast matching retrieval method. Background technique [0002] Since the 21st century, with the rapid development of the textile industry, fabric products have been greatly enriched, providing sufficient resources for clothing design. But for fashion designers, it is extremely time-consuming and difficult to manually find the required fabrics from thousands of fabric image libraries. Fashion designers usually have three requirements when choosing fabrics for clothing design: one is to find the same fabrics in the fabric library; the other is to find fabrics with pattern categories, pattern space distribution or similar colors in the fabric library to inspire them more. Design inspiration; the third is that it can quickly retrieve fabric images in a massive fabric library. Existing manual methods are difficult to quickly achieve the above requirements.
