A Resource Efficient Fast Recovery Strategy for Survivable WDM Networks
Abstract: ABSTRACT In WDM networks when failure occurs, huge amount of data is lost in a fraction of second. Therefore, the failed connection request must be re-routed through backup route as soon as possible. For achieving fast connection recovery, the primary lightpath is either link or segmented protected. However, the strategies result in inefficient utilization of resources. In this paper, we present a resource efficient parallel signaling-shared path protection (PS-SPP) based …

Image Preprocessing Techniques
Abstract: ABSTRACTPreprocessing method is an important step, specifically for low-quality picture images. This method is robust to lighting variations and produces images with very little noise and consistent stroke width. The process computes a “surface” of background intensities at every point in the image that performs adaptive thresholding based on this result. The surface is estimated by identifying regions of low resolution text and interpolating neighboring background intensities into these regions. …
