Abstract In this paper,a method for target recognition from natural scene images based on morphological reconstruction is presented and used to solve the problem of target recognition of the ground scene. Firstly, the definitions of grayscale reconstruction are illustrated and their performance evaluation for background suppression is demonstrated, and an input image is processed using morphological grayscale reconstruction. Then, the processed image is segmented and regions of interest are obtained. Lastly, the target is recognized by features extraction for regions of interest and matching based on model features of the target. The experiment results show that the proposed method can effectively recognize the target from complex natural scene.
