ARTICLE NO. IV960517 Image Registration Using a New Edge-Based Approach

A new edge-based approach for efficient image registration of a scene [9]. There are two tasks which need to be handled during an image registration process. They are feature is proposed. The proposed approach applies wavelet transform selection and correspondence establishment. Typically, to extract a number of feature points as the basis for registration. Each selected feature point is an edge point whose edge response is the maximum within a neighborhood. By using a line-fitting model, all the edge directions of the feature points are estimated from the edge outputs of a transformed image. In order to estimate the orientation difference between two partially over-lapping images, a so-called ‘‘angle histogram’ ’ is calculated. From the angle histogram, the rotation angle which can be used to compensate for the difference between two target images feature points can be selected by manual or automatic methods [1, 6, 10]. However, automatic selection of featur
