散离噪声通常位于邻域内正确值的两端。 (a) original image with Gaussian noise; (b) Gaussian filtered; (c) median filtered; (d) bilaterally filtered; (e) original image with shot noise; (f) Gaussian filtered; (g) median filtered; (h) bilaterally filtered. 中值滤波、阿尔法截尾法中值滤波、加权...
Non Linear Spatial Filtering: Order-statistic filters are nonlinear spatial filters whose response is based on filters whose response is based on ordering (ranking) the pixels contained in the image area. The best known filter in this category is the median filter, which as its name implies, re...

tries to investigate, the application of the Residue Number System in Digital Image Processing and propose a scheme in digital image filtering of spatial domain based on the Residue Number System using the integration circuits with high speeds and security and low power for Digital Image Processing....
The collapse of a laser beam propagating inside a hollow-core fiber is investigated by numerically solving different nonlinear propagation models. We have identified that the fiber confinement favors the spatial collapse, especially in case of pulses wit
