Available in PDF, EPUB and Kindle. Book excerpt: This research is aimed at developing efficient dim object tracking techniques in cluttered image sequences. In this dissertation, a number of new techniques are presented for image enhancement, super resolution (SR), dim object tracking, and multi-sensor object tracking. Cluttered images are impaired by noise. To deal with a mixed Gaussian and impulse noise in the image, a novel sparse coding super resolution is developed. The sparse coding has recently become a widely used tool in signal and image processing. The sparse linear combination of elements from an appropriately chosen over-complete dictionary can represent many signal patches. The proposed SR is composed of a Genetic Algorithm (GA) search step to find the optimum match from low resolution dictionary. By using GA, the proposed SR is capable of efficiently up-sampling the low resolution images while preserving the image details. Dim object tracking in a heavy clutter environment is a theoretical and technological challenge in the field of image processing. For a small dim object, conventional tracking methods fail for the lack of geometrical information. Multiple Hypotheses Testing (MHT) is one of the generally accepted methods in target tracking systems. However, processing a tree structure with a significant number of branches in MHT has been a challenging issue. Tracking high-speed objects with traditional MHT requires some presumptions which limit the capabilities of these methods. In this dissertation, a hierarchal tracking system in two levels is presented to solve this problem. For each point in the lower-level, a Multi Objective Particle Swarm Optimization (MOPSO) technique is applied to a group of consecutive frames in order to reduce the number of branches in each tracking tree. Thus, an optimum track for each moving object is obtained in a group of frames. In the upper-level, an iterative process is used to connect the matching optimum tracks of the consecutive frames based on the spatial information and fitness values. Another problem of dim object tracking is background subtraction which is difficult due to noisy environment. This dissertation presents a novel algorithm for detecting and tracking small dim targets in Infrared (IR) image sequences with low Signal to Noise Ratio (SNR) based on the frequency and spatial domain information. Using a Dual-Tree Complex Wavelet Transform (DT-CWT), a Constant False Alarm Rate (CFAR) detector is applied in the frequency domain to find potential positions of objects in a frame. Following this step, a Support Vector Machine (SVM) classification is applied to accept or reject each potential point based on the spatial domain information of the frame. The combination of the frequency and spatial domain information demonstrates the high efficiency and accuracy of the proposed method which is supported by the experimental results. One of the important tools applied in this dissertation is Particle Filter (PF). The PF, a nonparametric implementation of the Bayes filter, is commonly used to estimate the state of a dynamic non-linear non-Gaussian system. Despite PF's successful applications, it suffers from sample impoverishment in real world applications. Most of the recent PF based techniques try to improve the functionality of the PF through evolutionary algorithms in the cases of unexpected changes in the system states. However, they have not addressed the discontinuity of observation which is unpreventable in the real world. This dissertation incorporates a recently developed social-spider optimization technique into PF to overcome the drawback of previous methods in these cases. The problem of object tracking using multi-sensor data is a theoretical and technological challenge in the field of image processing which is presented as the final algorithm in this dissertation. Most of the conventional multi-sensor methods fail to track small dim objects in a cluttered background due to the lack of geometrical target information and unexpected large discontinuities in the measurement data. In this dissertation, a multi-sensor Swarm Intelligence Particle Filter (SIPF) is proposed in an environment covered by a set of multiple calibrated sensors with overlapping field of views. The proposed hierarchical method is divided into two levels. In the lower-level, SIPF is applied to locate the targets in each sensor based on the prior information. Each sensor reports the target position and its related fitness value to a dynamically selected central sensor. In the upper-level, the central sensor finds the best of the reported position for each target and broadcasts its position to all sensors at the lower level as the actual position of the target. Experimental results show this method is able to utilize multi-sensor data to produce highly accurate tracks in noisy datasets even in the case of large jumps or discontinuous observations well beyond the conventional tracking methods..

Available in PDF, EPUB and Kindle. Book excerpt: Sequential Analysis: Hypothesis Testing and Changepoint Detection systematically develops the theory of sequential hypothesis testing and quickest changepoint detection. It also describes important applications in which theoretical results can be used efficiently. The book reviews recent accomplishments in hypothesis testing and changepoint detection both in decision-theoretic (Bayesian) and non-decision-theoretic (non-Bayesian) contexts. The authors not only emphasize traditional binary hypotheses but also substantially more difficult multiple decision problems. They address scenarios with simple hypotheses and more realistic cases of two and finitely many composite hypotheses. The book primarily focuses on practical discrete-time models, with certain continuous-time models also examined when general results can be obtained very similarly in both cases. It treats both conventional i.i.d. and general non-i.i.d. stochastic models in detail, including Markov, hidden Markov, state-space, regression, and autoregression models. Rigorous proofs are given for the most important results. Written by leading authorities in the field, this book covers the theoretical developments and applications of sequential hypothesis testing and sequential quickest changepoint detection in a wide range of engineering and environmental domains. It explains how the theoretical aspects influence the hypothesis testing and changepoint detection problems as well as the design of algorithms.

Available in PDF, EPUB and Kindle. Book excerpt: "This thesis explores three object tracking algorithms for image sequences. These algorithms include the ensemble tracker, the EM-like mean-shift colour-histogram tracker, and the wandering-stable-lost scale-invariant feature transform (WSL-SIFT) tracker. The algorithms are radically different from one another. Despite their differences, they are evaluated on the same publicly available, moderately sized, research data sets which include 129 test cases in 13 different scenes. The results aid in fostering an understanding of their respective behaviours and in highlighting their flaws and failures. Lastly, an implementation setup is described that is suited to large-scale, grid computing, batch testing of these algorithms. Results clearly indicate that none of the evaluated trackers are suited to general purpose use. However, one may intelligently choose a tracker for a well-defined application by analysing the known scene characteristics." --

Download or read book Tracking a Rigid Object Along Image Sequences Using a Three Frame Matching Primitive written by Erez Shilat and published by . This book was released on 1996 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Motion tracking is a fundamental capability in the processing of image sequences. Tracking methods which use assumptions on the type of motion in the image sequence (e.g. spatial or temporal smoothness) are limited in their applicability. Tracking methods based on the processing of pairs of images are not very reliable. In this paper we present a highly reliable method for tracking features of a rigid object along image sequences obtained by an uncalibrated projective camera. The method is based on a three-frame matching primitive. There are no assumptions regarding the geometry of the scene or the temporal or spatial smoothness of the flow field between the frames. Relatively large displacements between the frames can be handled. The method is not sensitive to specular reflections, highlights, and small moving objects. It can be used in an incremental, on-line fashion where the images are given one at a time."
