Abstract:
A method for trademark figurative element identification is disclosed, including: establishing a sample trademark library and establishing a corresponding relationship between sample trademarks and division data for figurative element codes of known filed/registered figurative trademarks; extracting and processing 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 image feature information of a trademark to be identified; performing a matching retrieval by taking the image feature information of the trademark to be identified as a retrieval condition, and finding out a sample trademark with a highest similarity degree to the image feature information of the trademark to be identified, and a corresponding trademark figurative element code; outputting the trademark figurative element code corresponding to the sample trademark as a figurative element code of the trademark to be identified. By means of the method, the trademark figurative element codes of a figurative trademark can be automatically divided.

Claim (Index 14):
The device according to  claim 12 , wherein, the sample trademark image feature information extraction module and the image feature information extraction module for the trademark to be identified respectively include:\n a trademark preprocessing sub-module, configured to preprocess the trademark by at least one of graying, binarization, and denoising; a contour feature line extraction sub-module, configured to extract a contour feature line of the preprocessed trademark image, wherein the contour feature line includes a set of pixels in an edge, a set of pixels in an outer contour line, and a set of pixels in an inner contour line of the trademark image; a contour feature line positioning sub-module, configured to position a direction and an extracting rectangle of the contour feature line in a coordinate system, wherein the coordinate system is constructed by taking a single pixel of an image as a measurement unit on an x axis and a y axis; a pixel coordinate value extraction sub-module, configured to extract a coordinate value G n  (x n , y n ) of a pixel in the contour feature line in the coordinate system, wherein a subscript n represents art nth pixel; a relative coordinate value obtaining sub-module, configured to represent the coordinate value G n (x n , y n ) by a relative number according to a preset rule, to obtain a relative coordinate value S n (x n , y n ), wherein values of x n  and y n  in S n  are represented by relative numbers (percentages), and values of x n  and y n  in G n  are represented by absolute numbers; a rounded relative coordinate value obtaining sub-module, configured to round the relative coordinate value S n (x n , y n ) according to a preset distortion tolerance parameter and a rounding rule of \u201cround off\u201d, to obtain a rounded relative coordinate value Z n (x n , y n ); a coordinate value data outputting and processing sub-module, configured to output and store the obtained relative coordinate value S n (x n , y n ) and rounded relative coordinate value Z n (x n , y n ); a subfigure segment establishing sub-module, configured to establish a subfigure segment of the trademark image; and an image feature information extraction sub-module, configured to extract and process image feature information of the subfigure segment, to obtain a relative coordinate value S n (x n , y n ) and a rounded relative coordinate value z n (x n , y n ) of the subfigure segment.
