Abstract :
The resistance of a resistor is defined by colored lines printed on the resistor´s body. Normally, people read it by sight Though, if a computer performs this instead, we can reduce the costs. We have proposed a method for reading the resistor by image processing techniques. However, color features for reading a resistor is little studied. In this paper, we examine 10 color features (RGB, XYZ, YCbCr, YIQ, HSI, HSV, HLS, L* u* v*, L* a* b*, and I1I2I3) in order to read the resistor´s colors. The experimental results show the special effectiveness of the L* u* v* color feature.
