A Scale-Preserving Lens Distortion Model and its Application to Image Registration

A Novel Method for Measuring, Regardless of Image Distortion and Lens Varying Specifications in Endoscopic Treatment of Vesicoureteral Reflux

Image Registration and Mosaicing using a Self-Calibrating Camera

We introduce a new approach for the solution of three interrelated problems: Image registration, mosaicing and camera calibration. First we use well known similarity measures with particular interest in enhancing the performance for image registration. After initial registration we use a camera model to reene the alignment updating estimated camera parameters. A relaxation method applied on thi...

A Scale Space Method for Volume Preserving Image Registration

Image registration is an inherently ill-posed problem. Therefore one typically aims to provide as much information about the underlying application as possible. In particular for tumor monitoring, volume preservation of the wanted deformation is a central point. Based on [1], we propose a new scale space approach to volume preserving image registration. The main advantage of the new approach is...

Multi-frame Super Resolution for Improving Vehicle Licence Plate Recognition

License plate recognition (LPR) by digital image processing, which is widely used in traffic monitor and control, is one of the most important goals in Intelligent Transportation System (ITS). In real ITS, the resolution of input images are not very high since technology challenges and cost of high resolution cameras. However, when the license plate image is taken at low resolution, the license...

Pairwise retinal image registration by radial distortion correction

We describe a new method for pairwise retinal image registration. The proposed method is unique in that the radial distortion due to image acquisition is corrected prior to the geometric transformation. Since the overlapping region is typically small in a retinal image pair, only a few correspondences are available, thus limiting the applicable model to an affine transform at best. To recover t...
