Images Segmentation Method Based on A Multi Scale Analysis of 2D Histograms

--In this paper we propose an image segmentation method based on multi-scale analysis using wavelets, this method has been developed and adapted to detect road signs (road signs and traffic lights). It is an approach to highlight objects in a road scene especially objects corresponding to a road signs. It relies on the use of 2D histograms highlighting the different modes and based on operation of multi-scale representations of an image with an analysis with wavelets. That said the identification of colors with weak presence in the image as well as the relevant discrimination of different colors in the image, which discriminates objects of the same color visually. Keywords--wavelet transforms multi resolution, segmentation, 2D histogram.
