A computer-based spatial-filtering velocimeter to measure the surface velocity of natural debris flow is described. This is a simple and interesting technique implemented with a spatial filter constructed as a software program that processes the video image of debris flow instead of a hardware implementation. The surface velocity of the debris flow at the(More)
An adaptive computer-based spatial-filtering velocimeter to measure the surface velocity of a natural debris flow with high accuracy is described that can adjust the filter parameters, specifically, the slit width of the filter, based on the surface-pattern characteristics of the flow. A computer simulation confirms the effectiveness of this technique. The(More)
Optical fiber networks have been emerged to be the backbone of global communication infrastructure in present world. But, they are currently experiencing an unprecedented level of stress in order to meet the demand of increasing bandwidth-hungry applications. Moreover signals are frequently subjected to distortion due to optical fiber impairments while(More)
