We investigate the problem of combining or aggregating several color values given in coding scheme RGB. For this reason, we study the problem of averaging values on lattices, and in particular on discrete product lattices. We study the arithemtic mean and the median on product lattices. We apply these aggregation functions in image reduction and we present a new algorithm based on the minimizat...

When two sequential video frames extracted from a single video clip are followed by the negative of the two frames, a viewer often experiences a visual illusion whereby a scene in the frames continuously moves in a single direction (four-stroke apparent motion). To create a four-stroke apparent motion display, the image intensities of the whole of the second pair of images are reversed. However...

This paper presents two fuzzy filters for the removal of both Impulse and Gaussian noise in color images. A combination of these two filters also helps in eliminating a mixture of these two noises. For dealing with the Impulse noise, an algorithm is developed to search for a set of uncorrupted pixels in the neighbourhood of the pixel of interest (i.e. the central pixel) and to compute the media...

interaction of floral pigments with metal ions can alter the final color of the petals. metal ions can affect stability of flowers final color by altering vacuolar ph and activity of enzymes involved in biosynthesis, destruction, accumulation and transition of pigments. in this study, contents of metal ions of petal tissue and their relationships with parameters of petal color analyzed and comp...

In this paper a new approach to the problem of impulsive noise reduction in color images is presented. The basic idea behind the new image 6ltering technique is the maximization of the similarities between pixels in a prede6ned 6ltering window. The improvement introduced to this technique lies in the adaptive establishing of parameters of the similarity function and causes that the new 6lter ad...
