The generation reason and mathematical distribution model of noise in the image obtained by UAV are briefly analyzed
and a hybrid denoising method for Gaussian-impulse mixed noise is proposed and the practical application effect of the method is test by using ASIFT matching algorithm.The method can be described as follows:Firstly
remove the impulse noise of image by adaptive median filter.Secondly
OWT SURE-LET algorithm is utilized to denoise the Gaussian white noise.Experimental results show that the algorithm has stable image matching effect with less computation time.
