Automatic Ship Detection in Space-borne Sar Imagery
Synthetic aperture radar (SAR) imagery has proven to be a promising data source for the surveillance of maritime activity, and its application for automatic ship detection has been the focus of many research studies. Apart from the well-known CFAR detector, there has emerged a novel method for automatic ship detection, based on the wavelet transform. Since the underlying principles for both met...
متن کاملShip Detection in SAR Imagery
Abstract---As a part of Maritime Domain Awareness, there is a requirement to detect ships in satellite-borne Synthetic Aperture Radar (SAR) images, which provide wide area ocean surveillance. When ship detection is implemented using a Constant False Alarm Rate (CFAR), statistical theory can be employed to ensure that proper parameters are used to find the thresholds for detection; inaccuracy ...
متن کاملShip Contour Extraction from SAR Image Slice
Synthetic Aperture Radar (SAR) target detection and identification technology is one of the choke points for SAR practical application, the key of which is effective feature extraction. In terms of high resolution SAR image, target identification performance can be improved if contour feature of target, one of main geometric structures, can be detected accurately. Therefore a method was propose...
متن کاملThe Extended Sub-look Analysis In Polarimetric SAR Data For Ship Detection
The monitoring of maritime areas with remote sensing is essential for security reasons and also for the conservation of environment. The synthetic aperture radar (SAR) can play an important role in this matter by considering the possibility of acquiring high-resolution images at nighttime and under cloud cover. Recently, the new approaches based on the sub-look analysis for preserving the infor...
متن کاملA Hierarchical Classification Method for Breast Tumor Detection
Introduction Breast cancer is the second cause of mortality among women. Early detection of it can enhance the chance of survival. Screening systems such as mammography cannot perfectly differentiate between patients and healthy individuals. Computer-aided diagnosis can help physicians make a more accurate diagnosis. Materials and Methods Regarding the importance of separating normal and abnorm...
