A fast 2D shape recovery approach by fusing features and appearance.
29 Jun 2009 
In this paper, we present a fusion approach to solve the nonrigid shape recovery problem, which takes advantage of both the appearance information and the local features. We have two major contributions. First, we propose a novel progressive finite ...

Combining slanted-frame classifiers for improved HMM-based Arabic handwriting recognition.
29 Jun 2009 The problem addressed in this study is the offline recognition of handwritten Arabic city names. The names are assumed to belong to a fixed lexicon of about 1,000 entries. A state-of-the-art classical right-left hidden Markov model (HMM)-based ...

Classification based on hybridization of parametric and nonparametric classifiers.
29 Jun 2009 Parametric methods of classification assume specific parametric models for competing population densities (e.g., Gaussian population densities can lead to linear and quadratic discriminant analysis) and they work well when these model assumptions ...

A constant-time algorithm for finding neighbors in quadtrees.
29 Jun 2009 Quadtrees and linear quadtrees are well-known hierarchical data structures to represent square images of size 2(r) x 2(r). Finding the neighbors of a specific leaf node is a fundamental operation for many algorithms that manipulate quadtree data ...

A unified hydrophobicity scale for multispan membrane proteins.
29 Jun 2009 The concept of hydrophobicity is critical to our understanding of the principles of membrane protein (MP) folding, structure, and function. In the last decades, several groups have derived hydrophobicity scales using both experimental and ...

29 Jun 2009 OBJECTIVE: The purpose of our study was to determine the sensitivity of CT colonography (CTC) interpreted by human readers and with computer-aided detection (CAD) for genuinely nonpolypoid colorectal lesions, defined as 2 mm or less in lesion height ...

Pattern recognition of benign nodules at ultrasound of the thyroid: which nodules can be left alone?
29 Jun 2009 OBJECTIVE: The purpose of this study was to evaluate morphologic features predictive of benign thyroid nodules. MATERIALS AND METHODS: From a registry of the records of 1,232 fine-needle aspiration biopsies performed jointly by the cytology and ...

Validation-based sparse Gaussian process classifier design.
29 Jun 2009 Gaussian processes (GPs) are promising Bayesian methods for classification and regression problems. Design of a GP classifier and making predictions using it is, however, computationally demanding, especially when the training set size is large. ...

Non-diffeomorphic registration of brain tumor images by simulating tissue loss and tumor growth.
29 Jun 2009 Although a variety of diffeomorphic deformable registration methods exist in the literature, application of these methods in the presence of space-occupying lesions is not straightforward. The motivation of this work is spatial normalization of MR ...

28 Jun 2009 In this paper, we present a new recurrent bidirectional model that encompasses correlational, competitive and topological model properties. The simultaneous use of many classes of network behaviors allows for the unsupervised learning/categorization ...
