ItemRetinal Image Matching Using Hierarchical Vascular Features(HINDAWI LTD, 2011)We propose a method for retinal image matching that can be used in image matching for person identification or patient longitudinal study. Vascular invariant features are extracted from the retinal image, and a feature vector is constructed for each of the vessel segments in the retinal blood vessels. The feature vectors are represented in a tree structure with maintaining the vessel segments actual hierarchical positions. Using these feature vectors, corresponding images are matched. The method identifies the same vessel in the corresponding images for comparing the desired feature(s). Initial results are encouraging and demonstrate that the proposed method is suitable for image matching and patient longitudinal study.

ItemAnti-personnel landmine detection based on GPR and IR imaging: a review( 2006-04)Ground penetrating radar (GPR) and Infrared (IR) camera have become two established sensors for detecting buried anti-personnel mines (APM) which contain no or a little metal. This report reviews the detection techniques of APM using GPR and IR, and describes particular situations where each technique is feasible. We provide an analysis for fusion based detection and classification of APM. We discuss the GPR and IR data acquisition, signal processing and image processing methods. We also include a comparative study of these two sensors with respect to signal processing and target detection procedures. The report discusses the strengths and weaknesses of each of the sensors based on data capturing efficiency, overcoming environmental difficulties and sensor technology. Finally, we emphasize that a geometrical feature based sensor fusion, combining GPR and IR, for detection and classification of APM may be the most effective technique.
