Problems solved by technology

[0004] 1) Manual division of trademark graphic element codes, the low efficiency of division work and the huge consumption of work energy are obvious;
[0005] 2) The coding division of trademark graphic elements requires strong professionalism, and it is difficult for ordinary staff to accurately grasp the coding method of trademark graphic elements, which limits the wide application of graphic trademark retrieval
[0006] 3) Even if professionals carry out the coding division of trademark graphic elements, there will be differences in the subjective judgment of trademark images by different professionals, and this difference will cause inconsistency in the coding of trademark graphic elements

Embodiment 1

[0077] Embodiment 1: If the relative coordinate value S of a group of pixel points on the contour feature line of a certain sample trademark image is obtained n (x n ,y n )as follows:

[0078] S 1 (0%, 52.321%), S 2 (0.891%, 51.567%), S 3 (2.189%, 50.463%), S 4 (3.986%, 49.646%), S 5 (4.895%, 47.347%), S 6 (6.263%, 45.396%), S 7 (8.231%, 43.373%), S 8 (9.172%, 41.502%), S 9 (11.265%, 38.674%).

[0079] Taking the deformation tolerance parameter i as 2% as an example, perform rounding according to the rounding rule of "not half-rounded, more than half-in" to obtain the rounded relative coordinate value Z of the above pixel points after the deformation tolerance is accurate n (x n ,y n )as follows:

[0080] Z 1 (0%, 52%), Z 2 (0%, 52%), Z 3 (2%, 50%), Z 4 (4%, 50%), Z 5 (4%, 48%), Z 6 (6%, 46%), Z 7 (8%, 44%), Z 8 (10%, 42%), Z 9 (12%, 38%).

[0081] ⑧ The rounded relative coordinate value Z of the pixel point after accurate rounding n (x n ,y n ) outp...

Abstract

The invention discloses a trademark graph element identification method. The method comprises the following steps: establishing a sample trademark library and establishing a corresponding relationship between sample trademarks and known registration-applied graph trademark graph element code division data; extracting and processing the image feature information of the sample trademarks and establishing a corresponding relationship between the sample trademarks and the extracted image feature information; extracting and processing the image feature information of a to-be-identified trademark; taking the image feature information of the to-be-identified trademark as a search condition to carry out matching search and finding out a sample trademark which is mostly approximate to the image feature information of the to-be-identified trademark and a trademark graph element code corresponding to the sample trademark; and outputting the trademark graph element code corresponding to the sample trademark as a graph element code of the to-be-identified trademark. According to the method, the trademark graph element codes of the trademark graphs can be automatically divided.

Description

technical field [0001] The invention relates to the field of trademark information retrieval, in particular to a method, device and system for identifying graphic elements of a trademark. Background technique [0002] Trademark search is an important task in procedures such as registration application, trademark examination, trademark management, and trademark rights protection. The traditional graphic trademark retrieval basically achieves the purpose of retrieval by manually inputting the trademark graphic element code as the retrieval condition. The coding of figurative elements of trademarks is a tool for dividing figurative elements of trademarks according to the "Vienna Agreement on the Establishment of the International Classification of Figurative Elements of Trademarks". and the name of the graphic element of the trademark. Therefore, the code of each trademark graphic element represents the content meaning of the trademark graphic element. [0003] At present, i...
