Image enhancement using color and spatial information

In this paper, a new filter that is performing color image enhancement is presented. The filter is achieving this through the minimization of a weighted cost function. The weights are determined using potential functions which are calculated in such a way as to convey spatial information. Application of the proposed filter on a real blurred and noisy color image is performed to verify its enhan...

Image Enhancement Algorithm Using Color Stereopsis

This paper propose a new image enhancement algorithm using color stereopsis between red and blue colors and also shows it’s advantages over depth darkening algorithm. Color stereopsis is a phenomenon in the human visual system (HVS) in which a long wavelength color is perceived as being located closer than a short wavelength color. Although many psychophysical studies on color stereopsis have b...

Image Source Separation Using Color Channel Dependencies

We investigate the problem of source separation in images in the Bayesian framework using the color channel dependencies. As a case in point we consider the source separation of color images which have dependence between its components. A Markov Random Field (MRF) is used for modeling of the inter and intra-source local correlations. We resort to Gibbs sampling algorithm for obtaining the MAP e...

Color image watermarking using channel-state knowledge

This work concentrates on the problem of watermarking embedding and blind optimum detection in full-frame DCT domain using channel-state knowledge concepts. Minimum length sequences are used to embed the watermark information in the color components. Each chip of the sequence is inserted in a random-like fashion in those coefficients that ensure imperceptibility, robustness and a very low proba...

Color Image Enhancement Using Multiscale Retinex and Image Fusion Techniques

Abstract—In this paper, an edge-strength guided multiscale retinex (EGMSR) approach will be proposed for color image contrast enhancement. In EGMSR, the pixel-dependent weight associated with each pixel in the single scale retinex output image is computed according to the edge strength around this pixel in order to prevent from over-enhancing the noises contained in the smooth dark/bright regio...
