Demosaicking: Color Filter Array Interpolation in Single-Chip Digital Cameras
Digital cameras have become popular and many people are choosing to take their pictures with digital cameras instead of film cameras. When a digital image is recorded, the camera needs to perform a significant amount of processing to provide the user a viewable image. This processing includes white balance adjustment, gamma correction, compression and more (reference “Color Image Processing Pip...
متن کاملW Adaptive Denoising of CFA Images for Image
In single sensor digital color cameras at each pixel it captures only one of the three primary colors so the full color image is obtained by interpolating all other missing color samples at that pixel this process is the color demosaicking process. When we capture the images using digital cameras there is some sensor noise is introduced in image. This type of noise is introduced in all type of ...
متن کاملICA based Image denoising for Single-Sensor Digital Cameras
MOST existing digital color cameras use a single sensor with a color filter array (CFA) to capture visual scenes in color. Since each sensor cell can record only one color value, the other two missing color components at each position need to be interpolated. The color interpolation process is usually called color demosaicking (CDM). The quality of demosaicked images is degraded due to the sens...
متن کاملSecure single-sensor digital camera
Introduction: Digital cameras are the most popular image acquisition device. Images taken with a digital camera are usually downloaded on a personal computer (PC) where they are watermarked [1] for copyright protection and ownership authentication prior to storage and re-distribution. However, this way provides a space that attackers can utilise to violate intellectual property and ownership ri...
متن کاملColor Filter Array Image Analysis for Joint Denoising and Demosaicking
A single-chip image sensor used in almost all consumer and in some professional-grade digital cameras today is affixed with an alternating pattern of spectrally shifted (in the electromagnetic wavelength sense) color filters to each pixel location. The arrangement of color filters, which are typically the canonical color triples (i.e. red, green, blue), is called color filter array (or CFA) [1,...
