Estimation of ship velocity by fusion of radon transformation with wavelet filters using SAR images
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2011, Vol 2, Issue 4
Abstract
Since monitoring of ship traffic is a routine exercise, it is thus desirable to develop computer-based algorithms to perform this task. It is well known that certain ships and wakes can be observed in the SAR .This paper broadens an appropriate logic for detection of the object causing the wake from the data collected to develop an appropriate algorithm for estimation of ship velocity. This works investigate the possibility in detecting ships and their wakes in the ERS Synthetic Aperture Radar (SAR) imagery. SAR processor usually assumes target to be stationary and by taking this advantage two existing techniques of wavelet filters with some innovation by radon transform is used to detect the ship wake and thus estimated the range velocity element. A method is erected to implement an effective structure to automatically segment the image after denoising with wavelet filters and accordingly use a manipulation process to calculate the velocity of the vessel. The output would be a systematic process of segmentation and an interactive method to detect the objects in an effective manner.
