摘要：【中文】本发明提供了一种图像形状特征描述符的获取方法及装置。其中方法包括步骤：S1，对图像色块连通域轮廓线平滑处理，获取平滑线向区间边界心轮线及相关数据；S2，将平滑线向区间的边界心轮线的起点、终点和图像重心点坐标按照预设标准像素尺寸进行坐标转换；S3，获取转换后线向区间边界心轮线的线长比例数和线向区间角度数比例数、转换后心心线线长比例数和心心线角度数比例数；S4，对上述的比例数进行数值区间分类，生成图像形状特征描述符。装置包括第一获取模块、转换模块、第二获取模块、生成模块。该方法及装置可提高图像检索的查全率、查准率，增强图像识别检索中相同或近似图像的匹配效果，且计算量较小、处理速度快。 【EN】The invention provides a method and a device for acquiring an image shape feature descriptor. The method comprises the following steps: s1, smoothing the contour line of the connected domain of the color block of the image, and acquiring a contour line of the boundary of the smooth line to the interval and related data; s2, converting coordinates of a starting point, an end point and an image gravity center point of a boundary center wheel line of the interval from the smooth line according to the size of a preset standard pixel; s3, acquiring the line length proportion number and the line interval angle proportion number of the converted line to the interval boundary heart wheel line, and the line length proportion number and the heart center angle proportion number of the converted heart center line; s4, performs numerical interval classification on the above-mentioned scale numbers, and generates an image shape feature descriptor. The device comprises a first acquisition module, a conversion module, a second acquisition module and a generation module. The method and the device can improve the recall ratio and the precision ratio of image retrieval, enhance the matching effect of the same or similar images in image identification retrieval, and have smaller calculated amount and high processing speed.
