Force Field Energy Functionals for Image Feature Extraction
Ears are an emergent biometric accruing application advantages including no requirement for subject contact and acquisition without demand. To recognize a subject's ear, we aim to extract a characteristic vector from a human ear image that may subsequently be used to identify or confirm the identity of the owner. Towards this end, a novel force field transformation and potential well extraction...
متن کاملForce ®eld Energy Functionals for Image Feature Extraction
The overall objective in de®ning feature space is to reduce the dimensionality of pattern space yet maintaining discriminatory power for classi®cation and invariant description. To meet this objective, in the context of ear biometrics, a novel force ®eld transformation has been developed in which the image is treated as an array of Gaussian attractors that act as the source of a force ®eld. The...
متن کاملForce field feature extraction for ear biometrics
The overall objective in defining feature space is to reduce the dimensionality of the original pattern space, whilst maintaining discriminatory power for classification. To meet this objective in the context of ear biometrics a new force field transformation treats the image as an array of mutually attracting particles that act as the source of a Gaussian force field. Underlying the force fiel...
متن کاملEar recognition based on force field feature extraction and convergence feature extraction
Ear recognition based on the force field transform is new and effective. Three different applications of the force field transform were discussed in this paper. Firstly, we discussed the problem in the process of potential wells extraction and overcame the contradiction between the continuity of the force field and the discreteness of intensity images. Secondly, an improved convergence-based ea...
متن کاملFeature Extraction for Image Mining
Due to the digitization of data and advances in technology, it has become extremely easy to obtain and store large quantities of data, particularly Multimedia data. Fields ranging from Commercial to Military need to analyze these data in an efficient and fast manner. Presently, tools for mining images are few and require human intervention. Feature selection and extraction is the pre-processing...
