20140348433 | IMAGE RECOGNITION METHOD AND DEVICE - The invention relates to the field of image processing technology, in particular to an image recognition method and device, for the purpose of solving such a problem in the prior art that lower recognition accuracy is resulted from loss of key information (except a contour drawing) in the image due to adoption of an image recognition mode for image representation based on a contour drawing. The embodiment of the invention provides an image recognition method, including: to determine the triangle matching degree on the basis of a characteristic triangle determinated from the target image and a characteristic triangle determinated from the source image; and to determine image matching degree between the target image and the source image on the basis of the triangle matching degree determinated. | 11-27-2014 |
