Circular Mean Filtering For Textures Noise Reduction
In this paper, a special preprocessing operations (filter) is proposed to decrease the effects of noise of textures. This filter using average of circular neighbor points (Cmean) to reduce noise effect. Comparing this filter with other average filters such as square mean filter and square median filter indicates that it provides more noise reduction and increases the classification accuracy...
متن کاملCumulant-Based Adaptive Multichannel Filtering for Wireless Communication Systems with Multipath RF Propagation Using Antenna Arrays
A method based on high-order statistics is proposed to mitigate the performance degradation caused by multipath RF propagation in a mobile radio communication system using a linear antenna array at the base-station receiver. It is shown that an overdetermined system of linear equations (involving only cumulants of the received baseband digitized signal) can be obtained to perform noniterative d...
متن کاملPixel-Based Skin Detection for Pornography Filtering
A robust skin detector is the primary need of many fields of computer vision, including face detection, gesture recognition, and pornography filtering. Less than 10 years ago, the first paper on automatic pornography filtering was published. Since then, different researchers claim different color spaces to be the best choice for skin detection in pornography filtering. Unfortunately, no com...
متن کاملClustering for Collaborative Filtering Applications
Collaborative ltering systems assist users to identify items of interest by providing predictions based on ratings of other users. The quality of the predictions depends strongly on the amount of available ratings and collaborative ltering algorithms perform poorly when only few ratings are available. In this paper we identify two important situations with sparse ratings: Bootstrapping a collab...
متن کاملAnisotropic Kuwahara Filtering with Polynomial Weighting Functions
In this work we present new weighting functions for the anisotropic Kuwahara filter. The anisotropic Kuwahara filter is an edge-preserving filter that is especially useful for creating stylized abstractions from images or videos. It is based on a generalization of the Kuwahara filter that is adapted to the local shape of features. For the smoothing process, the anisotropic Kuwahara filter uses ...
