Quickbird Remote Sensing Image Denoising Using Wavelet Packet Transform

Image denoising is the first pre-processing step in analyzing and understanding images, and is crucial to acquire the high-quality image products. QuickBird, launched in October 18, 2001, is the highest spatial resolution remote sensing image until now, and can be used in various fields. In order to take the benefit of the high spatial resolution information of the QuickBird panchromatic images, this paper proposed a method to remove the noise of QuickBird images based on the wavelet packet transform after analyzing the characteristics of wavelet packet transform. Experimental results show that wavelet packet transform performs effectively in removing the noise of QuickBird images compared with other methods.
