—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)
In this paper, an automatic road tracking method is presented for detecting roads from satellite images. This method is based on shape classification of a local homogeneous region around a pixel. The local homogeneous region is enclosed by a polygon, called the pixel footprint. We introduce a spoke wheel operator to obtain the pixel footprint and propose 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)
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)
Golgi phosphoprotein 3 (GOLPH3) has been validated as a potent oncogene involved in the progression of many types of solid tumors, and its overexpression is associated with poor clinical outcome in many cancers. However, it is still unknown the association of GOLPH3 expression with the prognosis of colorectal cancer (CRC) patients who received(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 examined whether physical and verbal aggression in the family of origin were associated with similar patterns of aggression in young adult couples. Hypotheses were tested using a sample of 213 focal individuals who were followed from adolescence to adulthood. Results suggested that aggression in the family when focal participants were(More)
