The methodology used to construct tree structured rules is the focus of this monograph. Unlike many other statistical procedures, which moved from pencil and paper to calculators, this text's use of trees was unthinkable before computers. Both the practical and theoretical sides have been developed in the authors' study of tree methods. Classification and Regression Trees reflects these two sides, covering the use of trees as a data analysis method, and in a more mathematical framework, proving some of their fundamental properties.

Data Mining - Concepts and Techniques.

The primary goal of pattern recognition is supervised or unsupervised classification. Among the various frameworks in which pattern recognition has been traditionally formulated, the statistical approach has been most intensively studied and used in practice. More recently, neural network techniques and methods imported from statistical learning theory have been receiving increasing attention. The design of a recognition system requires careful attention to the following issues: definition of pattern classes, sensing environment, pattern representation, feature extraction and selection, cluster analysis, classifier design and learning, selection of training and test samples, and performance evaluation. In spite of almost 50 years of research and development in this field, the general problem of recognizing complex patterns with arbitrary orientation, location, and scale remains unsolved. New and emerging applications, such as data mining, web searching, retrieval of multimedia data, face recognition, and cursive handwriting recognition, require robust and efficient pattern recognition techniques. The objective of this review paper is to summarize and compare some of the well-known methods used in various stages of a pattern recognition system and identify research topics and applications which are at the forefront of this exciting and challenging field.

Statistical pattern recognition: a review

Planning algorithms are impacting technical disciplines and industries around the world, including robotics, computer-aided design, manufacturing, computer graphics, aerospace applications, drug design, and protein folding. This coherent and comprehensive book unifies material from several sources, including robotics, control theory, artificial intelligence, and algorithms. The treatment is centered on robot motion planning but integrates material on planning in discrete spaces. A major part of the book is devoted to planning under uncertainty, including decision theory, Markov decision processes, and information spaces, which are the “configuration spaces” of all sensor-based planning problems. The last part of the book delves into planning under differential constraints that arise when automating the motions of virtually any mechanical system. Developed from courses taught by the author, the book is intended for students, engineers, and researchers in robotics, artificial intelligence, and control theory as well as computer graphics, algorithms, and computational biology.

extraction. This is in contrast to the early approaches of twoframe analysis. The use of long image sequences permitssome additional constraints like the continuity of motion tobe exploited provided that the frames are acquired at regularshort intervals of time. Motion analysis approaches usinglong image sequences are also more robust to noise due tothe redundancy of input data. This makes these approachesmore suitable for realistic applications.For motion analysis approaches using an extended imagesequence, it is very important that any motion discontinuityacross time be identified. This is independent of the goal ofmotion analysis, as such a detection of motion discontinuitywill permit the integration of desired information only fromthe appropriate part of the extended image sequence. As an

In one example embodiment, a system includes a first device configured to transmit a request for temporary user rights to media content; and a server configured to: receive the request from the first device, transmit, to a second device having full user rights to the media content, a notification that the server will issue the temporary user rights to the media content to a user account authenticated on the first device, receive, from the second device, an approval to issue the temporary user rights to the media content to the user account authenticated on the first device, issue the temporary user rights to the user account authenticated on the first device, and temporarily revoke the full user rights to the media content from a user account authenticated on the second device.

Image representation through local descriptors is the basis of numerous computer vision applications. In the past decade, many local image descriptors such as SIFT and SURF have been proposed, yet algorithms requiring low memory and computation complexity are still preferred. Binary descriptors such as BRIEF have been suggested to satisfy this demand, showing a comparable performance but much faster computation speed. In this paper, we propose a novel local image descriptor, LIPID, which employs intensity permutation and interval division to yield an effective performance in terms of speed and recognition. Our method is inspired by LUCID, proposed by Ziegler and Christiansen [8]. An extensive evaluation on the well-known benchmark datasets reveals the robustness and effectiveness of LIPID as well as its capability to handle illumination changes and texture images.

LIPID: Local Image Permutation Interval Descriptor

In this paper we present a new online learning and classification algorithm and suggest its use for image segmentation. Our learning algorithm follows a variation of Bayesian estimation procedure, which combines prior knowledge and knowledge learned from data. Our classification algorithm strictly follows a statistical classification procedure. The new online learning algorithm is simple to implement, robust to initial parameters and has a linear complexity. The experimental results using computer generated data show that the proposed online learning algorithm can quickly learn the underlying structure from data.
The proposed online learning algorithm is used to develop a novel image segmentation procedure. This image segmentation procedure is based on the region growing and merging approach. First, region growing is carried out using the online learning algorithm. Then, a merging operation is performed to merge the small regions. Two merging methods are proposed. The first method is based on statistical similarity and merges the statistically similar and spatially adjacent regions. The second method uses an information-based approach merging small regions into their neighbouring larger regions. Many experimental results clearly show the efficacy of the proposed image segmentation method.

This paper presents a generalization of the correspondence approach of Sethi and Jain by extending the path coherence criterion to high dimensional vector space. This allows the same correspondence procedure to be used for a variety of tokens including points, lines, planes and regions. To demonstrate the generalized approach, we apply it to track lines and present experimental results.
