A single sensor equipped with a color filter array (CFA) is used in many digital still cameras to capture any of the three primary color components, R(red), G(green) or B(blue) on each pixel location, in order to reduce the hardware cost. This single band is used to generate the true RGB image. Demosicing is the process of interpolating the missed colors, which aims to reconstruct the missing colors...
This paper presents a comprehensive study of the pixel-based skin color detection techniques. Two main issues of the skin detection are the selection of the best color space and skin color pixel classification algorithm. A large set of XM2VTS face database is used to examine whether the selection of color space can enhance the compactness of the skin class and discriminability between skin and non-skin...
Widely used digital cameras nowadays use single sensor color filter array (CFA) which captures only one component of a pixel among the three components red, green and blue (RGB). This interleaved RGB valued images are called mosaic images. The mosaic images are of one third of the RGB image's size. The mosaic image can be compressed further to reduce storage. In this paper we propose a new efficient...
In this paper, a new median based filtering algorithm is presented for the removal of impulse noise from digital images. A good analysis of the limitations of the top ranking median filters, the progressive switching median filter, PSMF and the rank-order based adaptive median filter, RAMF is made and are overcome very effectively by the proposed filter which cleans the impulse corruptions of a digital...
