Embodiment Construction

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Such as Figure 1-Figure 3 Shown, the present invention a kind of online search method based on the massive commodity image of stick figure interaction, comprises the following steps:

[0025] (1) Preprocessing a large number of product images, including contour extraction, feature point position and gradient direction calculation, and structure tensor calculation;

[0026] In order to better match the hand-painted stick figures, firstly, the edge contour extraction process should be performed on the product image, and then the feature points should be selected in the contour line, and the position and gradient description of the feature points should be obtained. In addition to the description of feature points, it is also necessary to calculate the structure tensor description of the image to improve the matching accuracy. In the present invention, the picture ...

Abstract

The invention discloses a method for searching massive clothes images in an online manner on the basis of stick figure interaction. The method has the advantages that feature description and piece quantity description are extracted for massive clothes image searching scenarios, feature indexes and commodity indexes are created, and a query service with a C / S (client / server) framework is created on the basis of the feature indexes and the commodity indexes; a query procedure includes steps of querying the feature indexes to acquire candidate sets and querying and reordering the commodity indexes to feed results, and the query efficiency and the query accuracy can be effectively integrated; drawing operation pages and asynchronous query interfaces are provided for clients, purchasing behavior can be directly generated according to the fed query results, and accordingly searching and purchasing requirements of users can be met.

Description

technical field [0001] The invention relates to the application field of mobile computing platforms, in particular to an online search method for mass clothing images based on stick figure interaction. Background technique [0002] With the development of mobile technology, more and more applications are migrated from traditional PC computers to smart mobile devices. Due to the portability and touch operation of mobile devices, hand-drawing operations can be easily realized. Therefore, combining device characteristics and e-commerce can realize innovative applications for searching and purchasing similar products based on hand-drawn stick figures. [0003] In the field of image retrieval based on sketching, Microsoft Research Asia proposed an image retrieval method based on hand-drawing and annotation in the paper "MindFinder: Image Search by Interactive Sketching and Tagging" published by Microsoft Research Asia in 2010, mainly using hand-drawn outlines , color and text an...
