—In this paper, a new two-step approach (detecting and pruning) for automatic extraction of road networks from aerial images is presented. The road detection step is based on shape classification of a local homogeneous region around a pixel. The local homogeneous region is enclosed by a polygon, called the footprint of the pixel. This step involves(More)
—In this paper, we propose a new framework to visualize hyperspectral images. We present three goals for such a visu-alization: 1) preservation of spectral distances; 2) discriminability of pixels with different spectral signatures; 3) and interactive visu-alization for analysis. The introduced method considers all three goals at the same time and produces(More)
We present a curve matching framework for planar open curves under similarity transform 1 based on a new scale invariant signature. The signature is derived from the concept of integral of unsigned curvatures. If one input curve as a whole can be aligned with some part in the second curve then the algorithm will find the requisite starting and end positions(More)
OBJECTIVES Although evidence suggests that physical disability and depression may be reciprocally related, questions of causality versus spuriousness and the direction of causality remain to be confidently answered. This study considered the hypothesis of reciprocal influence; the possibility of spuriousness in relation to pain, stress, and lifetime major(More)
We propose a new image registration scheme for remote sensing images. This scheme includes three steps in sequence. First, a seg-mentation process is performed on the input image pair. Then the boundaries of the segmented regions in two images are extracted and matched. These matched regions are called confidence regions. Finally, a non-linear optimization(More)
In regions of adult neurogenesis, neural progenitor cells (NPCs) are found in close proximity to blood vessels within a so-called 'vascular niche'. Neurogenesis is linked to angiogenesis via certain growth factors. We propose that angiopoietin-1 (Ang1), which is similar to VEGF, has a unique role in neurogenesis independent of its role in angiogenesis. In(More)
The present study examines reciprocal associations between marital functioning and adolescent maladjustment using cross-lagged autoregressive models. The research involved 451 early adolescents and their families and used a prospective, longitudinal research design with multi-informant methods. Results indicate that parental conflicts over child rearing(More)
Prevention of intimate partner violence on college campuses includes programs designed to change attitudes, and hence, a scale that assesses such attitudes is needed. Study 1 (N = 859) cross validates the factor structure of the Intimate Partner Violence Attitude Scale-Revised using exploratory factor analysis and presents initial validity data on the(More)
This study examined the link between parental divorce and marital conflict and young adult romantic relationships, and it tested whether offspring efficacy beliefs and conflict mediate this association. Young adults (N=358) provided data at three time points each separated by 7-week intervals. Results from structural equation modeling demonstrated that (a)(More)
In this paper we present a new algorithm to transform an RGB color image to a grayscale image. We propose using non-linear dimension reduction techniques to map higher dimensional color vectors to lower dimensional ones. This approach generalizes the gradient domain manipulation for high dimensional images. Our experiments show that the proposed algorithm(More)
