Nonlinear vector filtering for impulsive noise removal from color images
نویسندگان
چکیده
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 fast nd accurate approximation for the inverse cosine function is introuced. In addition, commonly used distance measures (Minkowski, ngular, and directional-distance) are analyzed and evaluated. Fially, suggestions are provided on how to choose a filter given cerain requirements. © 2007 SPIE and IS&T. DOI: 10.1117/1.2772639

Modified Central Weighted Vector Median Filter
A new filtering approach designed to eliminate impulsive noise in color images, while preserving fine image details is presented. The computational complexity of the new filter is significantly lower than that of the Central Weighted Vector Median Filter (CWVMF). The comparison shows that the new filter outperforms the CWVMF, as well as other standard procedures used in color image filtering fo...
متن کاملSimilarity based impulsive noise removal in color images
In this paper a novel approach to the problem of impulsive noise removal in color images based on the nonparametric density estimation is presented. The basic idea behind the new image filtering technique is the maximization of the similarities between pixels in a predefined filtering window. The new method is faster than the standard vector median filter and preserves better edges and fine ima...
متن کاملGeneralized adaptive vector sigma filters
In this paper we provide a new filtering scheme for the detection and the removal of impulsive noise in digital color images. The proposed adaptive nonlinear vector filters take the advantages of the robust order-statistic theory, generalized directional distance filter and standard sigma filter concept. The principles of the design are explained in detail. Simulation studies indicate that the ...

متن کاملUltrafast Technique of Impulsive Noise Removal with Application to Microarray Image Denoising
In this paper a novel approach to the impulsive noise removal in color images is presented. The proposed technique employs the switching scheme based on the impulse detection mechanism using the so called peer group concept. Compared to the vector median filter, the proposed technique consistently yields better results in suppressing both the random-valued and fixed-valued impulsive noise. The ...
