Color recognition

Color Based Object Recognition

The purpose is to arrive at recognition of multicolored objects invariant to a substantial change in viewpoint, object geometry and illumination. Assuming dichromatic reflectance and white illumination, it is shown that normalized color rgb, saturation S and hue H, and the newly proposed color models c 1 c 2 c 3 and l 1 l 2 l 3 are all invariant to a change in viewing direction, object geometry...

Color recognition with bacteriorhodopsin.

We have studied opto-electric properties of wild type bacteriorhodopsin and its two artificial variants. We have measured opto-electric responses with respect to wavelength for all three proteins and we describe the use of the proteins for color detection. Opto-electric responses of proteins to set of colored lights were measured and it has been shown that bacteriorhodopsin and its variants can...

Efficient Object Recognition Using Color

A real-time prototype system for identifying soda cans uses histogram indexing with only 16 colors, with excellent results. The final implementation identified cans almost perfectly, even on public display with many people attempting to fool it. Results from preliminary versions are presented, with a complete description of the circumstances used in training and testing the system. The final sy...

Discriminating Color Faces for Recognition

Color diagnosticity in object recognition

How does color influence object recognition? In this study a set of objects with three different color settings; appropriately colored, inappropriately colored or black and white, are used in an experiment to investigate the importance of color in object recognition. Objects are categorized as either man-made (e.g. furniture) or natural (e.g. fruit) and as high color diagnostic (HCD) or as low ...
