Face Recognition using Tchebichef Moments
Received July 12 th , 2012 Accepted July 28 th , 2012 In this paper, a new Face Recognition method based on Discrete orthogonal Tchebichef moments with Linear Discriminant Analysis and Probabilistic Neural Network is proposed. Tchebichef moments are having good energy compaction property that made them useful in image compression and dimensionality reduction operations. Moreover the translation...
متن کاملFace Image Retrieval using Tchebichef Moments
Image Retrieval is a field of study concerned with searching and retrieving images from a collection of database. Face image retrieval is still a challenging task since face images can vary noticeably in terms of facial expressions, lighting conditions etc. In this paper we propose a face image retrieval method using Orthogonal Moments (Tchebichef Moment). This method extracts the feature from ...
متن کاملFace Recognition Using Legendre Moments
The wide range of variations in human face due to view point, pose, illumination and expression deteriorate the recognition performance of the existing Face recognition systems. This paper proposes a new approach to face recognition problem using Legendre moments for representing features and nearest neighbor classifier for classification. The Legendre moments are orthogonal and scale invariant...
متن کاملTexture classification using discrete Tchebichef moments.
In this paper, a method to characterize texture images based on discrete Tchebichef moments is presented. A global signature vector is derived from the moment matrix by taking into account both the magnitudes of the moments and their order. The performance of our method in several texture classification problems was compared with that achieved through other standard approaches. These include Ha...
متن کاملFace Recognition Using Discrete Orthogonal Hahn Moments
One of the most critical decision points in the design of a face recognition system is the choice of an appropriate face representation. Effective feature descriptors are expected to convey sufficient, invariant and non-redundant facial information. In this work we propose a set of Hahn moments as a new approach for feature description. Hahn moments have been widely used in image analysis due t...
