Haar and Local Binary Patterns

Based on previous work and some further reading, the program might be fine with the following implementation which takes Haar filters or their newer extension into account. Box diagram for the implementation in place can be seen in Figure .

Based on the paper titled ``Effective Traffic Lights Recognition Method for Real Time Driving Assistance System in the Daytime,'' Kim et al. use similar tools. The paper is quite recent and it too uses Haar filters. Before looking into this approach I also attempted to use template-based search; it is infeasible, however, because cars come in many shapes and sizes, not to mention colour and illumination, context, etc. The example template image (see Figure ) enables me to deal with something that in a mockup-type experiment³ would be easy to test, e.g. by putting the phone/tablet in front of a computer screen with the exact same static image on it.
