Nonlinear filtering in digital phase sensitive demodulation
Abstract. The phase sensitive demodulation has been widely used in many applications, e.g. impedance measurement, communication, sonar and radar systems. In most cases, white noise is assumed for system analysis and improvement. However, impulsive noise is frequently encountered in many applications, which imposes great challenges in these systems. The paper presents a novel nonlinear filter me...
متن کاملCircular 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 کاملNonlinear vector filtering for impulsive noise removal from color images
bstract. A comprehensive survey of 48 filters for impulsive noise emoval from color images is presented. The filters are formulated sing a uniform notation and categorized into 8 families. The perforance of these filters is compared on a large set of images that over a variety of domains using three effectiveness and one effiiency criteria. In order to ensure a fair efficiency comparison, a fas...
متن کاملEfficient impulsive noise suppression via nonlinear recursive filtering
A nonlinear recursive filter for the suppression of impulsive noises is proposed. This filter selects from each window a sample closest in value to the most recent output, and is thus named the lust output reference (LOR) filter. A relationship between the LOR and recursive median filters is derived, and some statistical properties are studied through computer simulations. The results indicate ...
