However, for more simple colour transforms, such as converting between different colour spaces (Rec709, P3, sRGB, etc) Matrices are more commonly used, although the data is often converted into 3D LUT form as fe
Logarithmic transforms are essential in several fields especially where there is a need to compress data that encompasses a vast dynamic range to a more manageable range for analysis and observation. The logarithmic transform reduces non-linear and non-separable forms to linearly separable forms. This...
In the case of defects showing little contrast or colour, black and white vision systems are inadequate and colour vision is needed. Colour entails a three-dimensional working space, thus permitting a series or geometric transforms of greater or lesser relevance depending on the specific application...
One such plug-in is "colormatcher exporter", within the "FotoTune" frame work (both are trade names of Agfa-Gevaert N.V. in Mortsel, Belgium), which transforms RGB data signals, obtained e.g. by scanning an original by a colour scanner, to CMYK data signals, ready for the printing ...
, 2006). Wavelet analysis is a signal processing technique for multi-resolution image texture analysis. It is performed by decomposing the images into multiple wavelet components using a filter bank as suggested by Mallat (1989). Using discrete wavelet transforms, image textures can be analysed at...
Any digital camera can retrieve the acquired scene in form of digital RGB data, but only as a the result of a mathematically delicate process that transforms the light occurring in the objective into presentation-ready digits—precisely the same process that can imply the compression and information...
