Demosaicing images from colour cameras for digital image correlation
Digital Image Correlation is not the intended use for consumer colour cameras, but with care they can be successfully employed in such a role. The main obstacle is the sparsely sampled colour data caused by the use of a colour filter array (CFA) to separate the colour channels. It is shown that the method used to convert consumer camera raw files into a monochrome image suitable for digital ima...
متن کاملClassification of Digital Cameras Based on Demosaicing Artifacts
In this paper, we consider using traces of demosaicing operation in digital cameras to identify the source digital camera-model of an image. For this purpose, we employ two methods and define a set of image characteristic. The first method detects simple forms of demosaicing based on extracting periodicity features, and the second method tries to estimate the demosaicing parameters assuming a l...
متن کاملDemosaicing of Colour Images Using Pixel Level Data-Dependent Triangulation
Single-chip digital cameras use an array of broadspectrum Charge-Coupled Devices (CCD) overlayed with a colour filter array. The filter layer consists of transparent patches of red, green and blue, such that each CCD pixel captures one of these primary colours. To reconstruct a colour image at the full CCD resolution, the ‘missing’ primary values have to be interpolated from nearby samples. We ...
متن کاملThe absolute sensitivity of digital colour cameras.
A new and improved method to obtain the average spectral pixel responsivity and the quantum efficiency of Digital Single Lens Reflex (DSLR) cameras is outlined. Two semi-professional cameras, the Nikon D300 and the Canon 40D, are evaluated. The cameras red, green and blue pixel responsivities and quantum efficiency are retrieved by illuminating an integrating sphere with a wavelength tunable mo...
متن کاملFlexible Storage of Images for Digital Cameras
Currently, digital still image cameras offer the user little flexibility. After initially selecting the number of images to be stored (from a limited number of possible settings), this selection cannot easily be changed at a later time. Furthermore, when only a few pictures have been taken, a large part of the storage capacity may remain unused (whereas it could have been used to improve image ...
