Implementation of the algorithm in test images showed that it is very effective in the sign location phase. There is a slight weakness in the some phase, in cases of color similarity between signs and other areas of the image. It is sensitive in light condition changes during the image acquisition, because of the effect they have in the color thresholds used in the regions of interest segmentation step. The use of proper thresholds is very important as it affects in a great deal the success of the sign detection and it’s final recognition. Based in the experience acquired from the tests, the aspects which should be further researched and be improved in the future are:
