Image registration is an important and fundamental task in image processing used to match two different images. Given two or more different images to be registered, image registration estimates the parameters of the geometrical transformation model that maps the sensed images back to its reference image. A feature-based approach to automated imageto-image registration is presented. The characte...

Locating the calibration markers of a chessboard is a prerequisite step to camera calibration. The efficiency and accuracy of this step has a crucial influence to the final results. This paper presents an automatic method for detection and location the internal corners of black and white squares by using Multi-Radon Transform (MRT) and image segmentation methods. The whole procedure mainly incl...

Analogous to the radar Doppler spectrum for coherent processing, the concept of a Radon spectrum that is a kind of normalised Radon transform is proposed and used for radar non-coherent detection. One advantage of using the Radon transform for non-coherent processing is that integration in all directions is considered, and hence range migration of moving targets is not a concern. The detection ...

Based on an all-optical system, a display of a fractional Fourier transform with many fractional orders is proposed. Because digital image-processing terminology is used, this display is known as the Radon-Wigner transform. It enables new aspects for signal analysis that are related to time- and spatial-frequency analyses. The given approach for producing this display starts with a one-dimensio...
