摘　　要：形状分析是指用计算机图像处理和分析系统对景物目标提取形状特征,对景物作识别、理解,区域形状特征的提取是形状分析的基础.图像区域具有平移、旋转和缩放无关的紧凑度(Compactness),无量纲的复合矩(moment),与位置和大小无关的归一化的傅立叶描述子(Fourier Descriptor)三个形状特征.The shape analysis is that feature extraction for contour shape and to recognise it using the system of computer image. Where the feature extraction contour shage is the basis for shape analysis. Compactness with independence for translation, rotation, and scale , compound moment that is dimensionless, normalized fourier descriptor with independence for position, size orientation, and starting point of the contour are proposed.

关 键 词：形状特征 紧凑度 矩 傅立叶描述子
