Abstract :
Outputs of an optical RGB sensor are adapted to CIE-XYZ color space coordinates. For this purpose, a correlation between the outputs of the sensor and the outputs of spectrophotometer is established. In order to test the performance of sensor, numerical data of some fabrics provided from various manufacturers are obtained by color analysis. Using advantages of computer-aided devices, a system is developed so that it can measure the color of various fabric samples by sensitively and fast. The measurements are made by a spectrophotometer and the optical color sensor, and then multiple linear regression analysis is applied to the results obtained. It is concluded that proposed method can be used as an alternative to the spectrophotometric method.
