This thesis investigates the issues of implementing multi-sensor imaging system for surveillance applications. Three topics for the fusion of infrared and electro-optic images are studied, i.e. registration, fusion, and evaluation. The first topic is the image registration or alignment, which is to associate corresponding pixels in multiple images to the same physical point in the scene. A trajectory-based method for registering infrared and electro-optic video sequences is proposed in this study. The initial registration parameters are derived from matching the trajectories across the consecutive video frames. Further refinement can be carried out by applying a maximum mutual information approach. The frame difference, from which the feature point is detected, is found with an image structural similarity measurement. The second topic is the implementation of pixel-level fusion. Two applications are considered in this study. Motivated by the adaptive enhancement, a modified pixel-level fusion scheme is proposed to implement the context enhancement. A visual image is first enhanced with the corresponding infrared image. Then, the enhanced image is fused with the visual image again to highlight the background features. This achieves a context enhancement most suitable for human perception. As the application of multi-sensor concealed weapon detection (CWD) is concerned, this thesis clarifies the requirements and concepts for CWD. How the CWD application can benefit from multi-sensor fusion is identified and a framework of multi-sensor CWD is proposed. A solution to synthesize a composite image from infrared and visual image is presented with experimental results. The synthesized image, on one hand provides both the information of personal identification and the suspicious region of concealed weapons; on the other hand implements the privacy protection, which appears to be an important aspect of the CWD process. The third topic is about the fusion performance assessment. In this study, the evaluation metrics are developed for reference-based assessment and blind assessment respectively. An absolute measurement of image features, namely phase congruency, is employed. Future work should include the reliability and optimization study of multiple image sensors from applications' and human perception-related perspectives. This thesis is a contribution to such research.

Taking another lesson from nature, the latest advances in image processing technology seek to combine image data from several diverse types of sensors in order to obtain a more accurate view of the scene: very much the same as we rely on our five senses. Multi-Sensor Image Fusion and Its Applications is the first text dedicated to the theory and practice of the registration and fusion of image data, covering such approaches as statistical methods, color-related techniques, model-based methods, and visual information display strategies. After a review of state-of-the-art image fusion techniques, the book provides an overview of fusion algorithms and fusion performance evaluation. The following chapters explore recent progress and practical applications of the proposed techniques to solving problems in such areas as medical diagnosis, surveillance and biometric systems, remote sensing, nondestructive evaluation, blurred image restoration, and image quality assessment. Recognized leaders from industry and academia contribute the chapters, reflecting the latest research trends and providing useful algorithms to aid implementation. Supplying a 28-page full-color insert, Multi-Sensor Image Fusion and Its Applications clearly demonstrates the benefits and possibilities of this revolutionary development. It provides a solid knowledge base for applying these cutting-edge techniques to new challenges and creating future advances.

Download Multi-sensor Imaging System Feasibility Study Book in PDF, ePub and Kindle
This report presents a survey of national and international markets to determine the availability of existing products for the development of an airborne multi-sensor day/night all-weather surveillance system. The sensors to be identified are a forward-looking infrared imager (FLIR), an ALBEDOS type active sensor, a laser rangefinder, and a charge coupled device (CCD) camera. The report provides a technical description of each type of sensor, along with associated theory, and then describes sensor requirements for four surveillance scenarios: identification of an automobile licence plate at 1 kilometre distance, identification of a ship at 2 kilometres, and detection of a person in water wearing a survival suit with retroreflective strips at 4 kilometres. Costs for an assembled multi-sensor system are also estimated. The appendix contains technical literature on various commercially available sensors.

Download Image Fusion for Surveillance Systems Book in PDF, ePub and Kindle
Image fusion is a process of combining complementary information from multiple images to generate a single image that is more suitable for the purpose of human visual perception or further image processing tasks. The source images can come from different types of sensors of the same basic type or they may come from different types of sensors. In our research, we focus on fusing images from different sensors. The application we mainly considered is the concealed weapon detection application (CWD) which utilizes multiple sensors to improve the identification of the person having weapons hidden underneath his clothing. CWD appears to be a critical technology for dealing with terrorism which is the most significant law enforcement problem for the next decade. In this dissertation, we focused on investigating three aspects of image fusion which have impact on the CWD application, with the hope of shedding more light on this promising area. First, we tested and compared the performance of a large set of typical image fusion algorithms for the CWD application using some typical quality measures. Based on the experimental results, it is clear that there is a need to develop new image fusion algorithms that are more effective for this specific application. In addition, most of the current image fusion work has been limited to monochrome images although the human vision system is very sensitive to colors. Thus, we proposed a new color fusion algorithm. Using the proposed method the fused image will maintain the high resolution and the natural color of the visual image while incorporating any useful information detected by the nonvisual sensor. The utility of the proposed method was demonstrated in the experimental tests. For multisensor image fusion, blind estimation of the image quality is of great interest and of great difficulty. Several objective image quality measures for image fusion have appeared, but there has been a lack of theoretical analysis on the performance of the quality measures. Thus, in this dissertation, we took a first step towards theoretically analyzing one of the popular quality measures, a mutual information based quality measure which had only been tested experimentally for a limited number of cases. We augmented these experimental tests with analysis.

Download Multi-Sensor Imaging and Fusion: Methods, Evaluations, and Applications, volume II Book in PDF, ePub and Kindle
Multi-sensor image fusion focuses on processing images of the same object or scene acquired by multiple sensors, in which various sensors with multi-level and multi-spatial information are complemented and combined to ultimately yield a consistent interpretation of the observed environment. In recent years, multi-sensor image fusion has become a highly active topic, and various fusion methods have been proposed. Many effective processing methods, including multi-scale transformation, fuzzy inference, and deep learning, have been introduced to design fusion algorithms. Despite the great progress, there are still some noteworthy challenges in the field, such as the lack of unified fusion theories and methods for effective generalized fusion, the lack of fault tolerance and robustness, the lack of benchmarks for performance evaluation, the lack of work on specific applications of multi-sensor image fusion, and so on.
