Description

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. In this paper, we propose a method for reading this resistance by image processing techniques. We extract colors from a real resistor's picture, and classify it by its colors. It is important to investigate the influence of illumination in classifying colors. The experiments are conducted under three types of illumination: dark, lighted, and well-lighted. Furthermore, we examine 10 color features (RGB, XYZ, YCbCr, YIQ, HSI, HSV, HLS, L^*u^*v^*, L^*a^*b^*, and I1I2I3) in order to classify resistor's colors. The experimental results show the effectiveness of the proposed method. From the results we understand a well illuminated environment is required. Also, the effectiveness of the L^*u^*v^*, L^*a^*b^*, and I1I2I3 color features is shown.
