PREPROCESSING METHOD FOR COLOR FILTERING ROBUST AGAINST ILLUMINATION ENVIRONMENT AND THE SYSTEM THEREOF

摘要

The present invention relates to a preprocessing method which preprocesses a color of road image to improve the concentration of the color and detects a traffic sign on a road environment using a fixed threshold value, and to a system thereof. By using the preprocessing method and the fixed threshold value, the performance of a hypothesis generation (HG) step of detecting a traffic sign can be improved and the non-classification (FN) of the traffic sign can be minimized.
