This paper proposes a traffic light detection
algorithm based on the morphological characteristics
of traffic light. In most studies, traffic light detection
is based on color. The problem with color-based
traffic light detection algorithm is that the traffic
light cannot be detected if the color of the traffic
light is changed by external factors. We propose a
traffic light detection algorithm based on the
morphological characteristics. The proposed method
can be applied to the traffic light detection regardless
of color changes.
