Full Restoration of Visual Encrypted Color Images
Traditional methods for visual cryptography have been established, are consistent and easily understood. Unfortunately, these methods exist for black and white pictures only, leaving the encryption of colour images wanting. While there are a handful of attempts at bringing colour to visual cryptography, it is still an open field with implementations of varying efficiency. In this paper, we will...
متن کاملRestoration of color images subjected to interchannel blurring
This paper deals with the restoration of colored images, distorted by both intraand inter-channel blur, and corrupted by additive white Gaussian noise. The image is modeled as a Markov Random Field (MRF), and color image restoration is cast as a maximum a posteriori (MAP) estimation problem. We propose a First Order Interchannel Interaction (FOII) model for image restoration. Simulated annealin...
متن کاملRegularized Multichannel Restoration of Color Images Using Cross-Validation
Multichannel images are the multiple image planes (channels) obtained by imaging the same scene using multiple sensors. The validity of multichannel restoration where both the within and between channel relations are incorporated has already been established using both stochastic and deterministic restoration filters. However, it has been demonstrated that stochastic multichannel filters are ex...
متن کاملDiving into Haze-Lines: Color Restoration of Underwater Images
Underwater images suffer from color distortion and low contrast, because light is attenuated as it propagates through water. The attenuation varies with wavelength and depends both on the properties of the water body in which the image was taken and the 3D structure of the scene, making it difficult to restore the colors. Existing single underwater image enhancement techniques either ignore the...
متن کاملColor Restoration of RGBN Multispectral Filter Array Sensor Images Based on Spectral Decomposition
A multispectral filter array (MSFA) image sensor with red, green, blue and near-infrared (NIR) filters is useful for various imaging applications with the advantages that it obtains color information and NIR information simultaneously. Because the MSFA image sensor needs to acquire invisible band information, it is necessary to remove the IR cut-offfilter (IRCF). However, without the IRCF, the ...
