This paper presents a new approach for region-based video mosaicing, treating moving objects separately from the background, and with improved ghost-like noise elimination. The mosaic images show the moving objects superimposed over a stationary background. Conventional technologies can reduce the ghost-like noise that occurs from moving objects by using temporal median filtering, but its effic...

This paper is concerned with amoeba median filtering, a structure-adaptive morphological image filter. It has been introduced by Lerallut et al. in a discrete formulation. Experimental evidence shows that iterated amoeba median filtering leads to segmentation-like results that are similar to those obtained by self-snakes, an image filter based on a partial differential equation. We investigate ...

In this paper we introduce a new class of nonlinear filters called Median-Rational Hybrid Filters (MRHF) based on Rational Functions (RF). The filter output is the result of a rational operation taking into account three sub-functions, such as two FIR or median subfilters and one center weighted median filter (CWMF). The proposed MRHF filters have the inherent property that on smooth areas they...

 A step-by-step algorithm for enhancement of periodic signals that are highly corrupted by additive uncorrelated white gausian noise is proposed. In each adaptation step a new parallel second-order section is added to the previous filters. Every section has only one adjustable parameter, i.e., the center frequency of the self-tuning filter. The bandwidth and the convergence factor of each secti...

A novel extension of the classical signal-adaptive median filter (SAM ) is proposed in this paper, namely the morphological signaladaptive median filter (MSAM ). Three modifications are introduced in the SAM filter aiming at: (1) enhancing the SAM impulse detection mechanism so that it also detects randomly-valued impulses, (2) employing an anisotropic window adaptation based on binary morpholo...

In this paper a novel adaptive noise attenuating and edge enhancing filter for color image processing is proposed. The new filtering design is based, like the vector median filter, on the minimization of aggregated weighted distances between pixels in a sliding filtering window. The weights which are assigned to the sequence of the sorted distances are decreasing functions of their ranks. In th...
