摘　　要：系统性地给出数字图像不变矩一般性构造方法,对不变矩冗余性进行分析。通过采用复数矩作为描述数字图像识别特征量的方法,研究复数不变矩所具有不变性的约束条件及其与几何不变矩间的关系,根据复数不变矩构造定理,给出判别复数矩冗余性的一般方法,并结合修正余弦相似度以实例对在工程应用中的采用低阶复数不变矩描述目标特征的有效性进行分析。研究结果表明:采用复数不变矩构造数字图像特征量具有很好普适性,对于图像目标识别特征的描述有较好的效果。To give the generalized methods of constructing digital image moment invariants and analysis its redundancy systematically,complex invariants are used for the methods of describing digital image recognition features. Constraint conditions of complex invariants and its relations between geometric moment invariants were discussed,and based on the complex moment invariants construction theorem the common way of redundancy judgment was given. Combined with the clustering cosine similarity and taking some low- order complex moment invariants in engineering application for examples,the validation of them is analyzed. Results indicate that,complex moment invariants have good universality in constructing digital image moment invariants features and perform well in image object recognition features description.
