متن کاملReal-time Median Filtering with a Fast Hardware Sorter
This work develops a hardware realization of a median filter suitable for use in real-time control and monitoring applications in power electronic circuits. Median filters have the ability to supprem impulse noise in signals while preserving underlying edges. The performance of the filter is demonstrated with results from a prototype.
متن کاملModification of the EEG time constant by digital filtering.
A method is proposed for modifying the time constant of an EEG amplifier after the recording. It is based on digital filtering and works for single sweeps, averaged potentials, and other neurophysiological data, e.g. spontaneous EEG. The validation is based on calibration signals and data from a study on eventrelated potentials. DESCRIPTORS: Time constant. Slow potentials, Digital filtering. We...
متن کاملApplication of Genetic Algorithm in Median Filtering
Images are often corrupted by impulse noise due to errors generate d in noisy sensors or communication channels. Two types of impulse noise can be defined: 1) fixed-valued and 2) random-valued. In many applications it is very important to remove noise in the images before some subsequent processing such as edge detection, object recognition and image segmentation. In this paper an adaptive filt...
متن کاملPreserving Median Filtering Algorithm in Chip Images
The types and characteristics of noise in chip images were analyzed in this paper. A new kind of details preserving adaptive median filtering algorithm with directional sub-window was introduced in which the shape and size of filtering window can be adjusted according to the noise level and the sensitivity can be set by parameter. The filter can effectively get rid of most of the impulse noise ...
