Embodiment Construction

[0037] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] A tie pattern retrieval method based on image edge feature analysis, comprising the following steps:

[0039] (1) Perform edge detection on the image of the tie to be retrieved to extract the contour of the image, and then quantify the edge features of the contour by calculating the gradient direction of the edge pixels.

[0040] The edge of the image is the area where the pattern and the pattern, the foreground and the background meet, and it is the most significant part of the change, which reflects the local discontinuity of the image, such as the sudden change of gray scale, the difference of texture, the difference of color, etc. Edge contour is the most important image invariant feature value, which has strong noise resistance and is often used...

Abstract

The invention discloses an image edge feature analysis-based necktie pattern retrieval method. The image edge feature analysis-based necktie pattern retrieval method comprises the following steps of: (1) performing edge detection on a design to extract the outline of the pattern of a necktie and quantify the outline as edge feature values; (2) analyzing the mathematical statistics features of edge feature value distribution, and dividing the pattern into three major categories of stripes, polygons and complex designs; and (3) matching patterns to be retrieved with patterns of the same type in a database, selecting a most similar pattern. The image edge feature analysis-based necktie pattern retrieval method of the invention is advantageous in no need for manual retrieval process, high-degree automation, high accuracy of retrieval results, fast speed and great universality, and can satisfy real-time application requirements, and can accurately classify different kinds of necktie patterns.

Description

technical field [0001] The invention belongs to the technical field of image processing and analysis, and in particular relates to a tie pattern retrieval method based on image edge feature analysis. Background technique [0002] With the continuous progress and development of science and technology and society, people's pursuit of clothing is also constantly improving. As an important part of commonly used clothes, neckties are constantly refurbished in styles, new varieties emerge in an endless stream, and patterns are varied. Many tie companies have thousands of patterns to tens of thousands of patterns, and thousands of new patterns can come out every day. With the development of e-commerce in tie manufacturers and the improvement of the automation of tie production and design, the traditional sample retrieval method can no longer meet the needs. The development of computer technology has improved the work efficiency of various industries. In the textile industry, comp...
