Embodiments of the invention relate to the determination of the colour of a colour sample from an image of the colour sample. In one embodiment a colour sample capture card is provided having printed thereon colour samples of known colour(for example, XYZ tri-stimulus values). An image of ...

To reconstruct a color image at the full CCD resolution, the 'missing' primary values have to be interpolated from nearby samples. We present an effective color interpolation using a simple pixel level data-dependent triangulation. This interpolation technique is applied to the commonly-used Bayer ...
Full size image An observation on frequency of eye colour from the Twins Eye Study in Tasmania and Brisbane showed there were more pale blue-eyed people in higher latitude Tasmania compared to subtropical Queensland, suggesting blue-eyed (and fair-skinned) immigrants may have chosen to avoid the...
Software realisation of a colour image recognition system with an image normalisation stage 来自 ResearchGate 喜欢 0 阅读量: 24 作者:R Holota,J Trejbal,BA Wilkie 摘要: The task of pattern recognition can be greatly facilitated if position, rotation and size normalisation are incorporated within the...
by the reading unit, an image forming unit (7) for forming a colour image based on a correction output from the correction unit, and a setting unit (22, 23) for setting a correction characteristic of the colour correction processing based on the colour image signal read by the reading ...
The invention provides a technique for correcting the saturation of an image signal. A characteristic detector detects a hue histogram of an input image signal showing the distribution of frequencies in each of plural hues in a given period of time. A colour correction unit corrects the saturation...
AT the last two annual exhibitions of the Royal Photographic Society, we have shown colour transparencies of the high-speed flow past aerofoils. In accounts in Nature of both exhibitions1, the method used in taking these photographs is erroneously descri
An image and texture viewer for tga, png, apng, exr, dds, pvr, ktx, ktx2, astc, pkm, qoi, gif, hdr, jpg, tif, ico, webp, and bmp files. Uses Dear ImGui, OpenGL, and Tacent. Useful for game devs as it displays information like the presence of an alpha cha
