Abstract
In a previous study, we examined color spaces to read resistor lines of 11 different colors (black, brown, red, orange, yellow, green, blue, purple, gray, white, and gold). However, the color classification experiment was carried out only under a certain illumination. In order effectively to classify real resistor color lines, the color classification under various illumination conditions must be considered. In this paper, we examine 10 color features (RGB, XYZ, YCbCr, YIQ, HSI, HSV, HLS, L*u*v*, L*a*b*, and I1I2I3) under the various illumination. The experimental results show the effectiveness of the L*u*v* color feature. Furthermore, in a very small training sample size situation, the classification performance of the u*v* feature vector except for an intensity element L* outperforms that of L*u*v*.
