Automatic Calibration, Acquisition, and Analysis for Color Experiments

This article is presenting a device for color experiments with automatic setup. The device is designed to carry on measurements of color of semi-homogenous objects. The light conditions are controlled by mikroPc and standardized for the experiments. The capturing camera setup and calibrations are done automatically using Gray World theory for white balance and defined background. The calibration is adjusted by brightness and contrast calibration, and difference between black and white versus light and dark. The device is connected with the software for automatic color analysis. The object is segmented from the background and transformed into several color space representations. The color channel distributions are statistically evaluated.
