A human observer is ready to realize the colour of items without reference to the sunshine used to light up them. this is often known as colour fidelity. A digicam makes use of a sensor to degree the mirrored mild, which means that the measured colour at every one pixel varies in accordance with the colour of the illuminant. accordingly, the ensuing shades will not be kind of like the colours that have been perceived through the observer. acquiring colour consistent descriptors from snapshot pixels isn't just very important for electronic images, but in addition beneficial for machine imaginative and prescient, color-based automated item popularity, and colour picture processing in general.
This publication offers a entire advent to the sphere of colour fidelity, describing all of the significant colour fidelity algorithms, in addition to providing leading edge learn within the quarter of colour photo processing. starting with an in-depth examine the human visible method, Ebner is going on to:
- examine the speculation of colour snapshot formation, colour copy and diverse colour spaces;
- discuss algorithms for colour fidelity less than either uniform and non-uniform illuminants;
- describe tools for shadow removing and shadow attenuation in electronic images;
- evaluate a number of the algorithms for item reputation and colour fidelity and examine this to info received from experimental psychology;
- set out different algorithms as pseudo code in an appendix on the finish of the book.
Color Constancy is a perfect reference for practicing engineers, desktop scientists and researchers operating within the quarter of electronic colour snapshot processing. it might even be valuable for biologists or scientists typically who're attracted to computational theories of the visible mind and bio-inspired engineering structures.
