A method for rectifying nonlinearity geometric distorted images based on genetic neural network is presented. Firstly, the genetic algorithm is used to optimize the weights of neural network and the genetic neural network is constructed. Then, the sample coordinates are extracted from a geometric distorted rectangular grid and are used to train the genetic neural network, and the sample coordinates from the original rectangular grid are used as the desired output values. Finally, all pixel coordinates from a distorted part image are regarded as the inputs of the genetic neural network and the gray level for all pixel coordinates of genetic neural network output is determined by gray-level interpolation to obtain non-linearity rectification of part image. Experimental results show that the method is effective for nonlinearity rectification of the part image.
