| 摘 要： | 提出一种新的基于图像形状的检索方法.首先,用Canny算子对图像进行平滑处理,提取图像边界方向直方图特征;其次,用改进的不变矩来描述图像形状的区域特征,改进后的不变矩特征不受图像的缩放、平移和旋转影响;最后,为了克服不变矩只针对对象区域而忽视图像边界的缺点,提出改进的不变矩与边界方向特征相结合的方法,使得检索取得更好的...

| Abstract: | A new kind of image retrieval method based on shape content was proposed.First,a Canny operator was used to smooth the source image and extract the feature of the edge direction histogram.Then,the improved invariant moments were used to describe the shape regional feature.The rotation,scaling-down or-up,and translation of images had no influence on those improved invariant moments.Finally,in order to overcome the shortcoming that invariant moments focus only on the region of image while overlook areas the s... |
