In this paper, it is presented an approach to automatic detection and recognition of signs from natural scenes, and its application to a sign recognition. The natural scene signs recognition is affected by the light changing, fading, being distorted on the surface of t signs. In this paper, a method is proposed that combined the improved scale invariant feature transform (SIFT) algorithm which reduces the high dimension and high complexity with Affine Scale Invariant Feature Transformation (ASIFT) algorithm under the natural scene sign detection and recognition. Experiments have proved that the method improved match number and matching time.
