Abstract:
Unmanned Aerial Vehicles (UAV) digital images are often badly degraded by noise during dynamic acquisition and transmission process. Denoising is very important and difficult for UAV-vision Guided, because natural scene image is complicated and having lots of the edges and texture details. The image denoising and enhancement algorithm based on adaptive dual-tree discrete wavelet packets(ADDWP) which combine the dual-tree discrete wavelet packets and evolutionary programming is proposed in this paper. In order to reduce the noise and enhance detail for a UAV image by the EP(evolutionary programming) in wavelet domain(.) Firstly, The de-noising threshold is estimated by EP in the wavelet domain. Secondly, Noise is reduced in the fine high-frequency sub-bands of each decomposition level, respectively, so that the maximum signal-noise ratio can be obtained in the high-frequency subbands, respectively. Thirdly, The enhancement parameters is estimated by EP in the wavelet domain, and the detail is adaptive enhanced by an improved non-linear gain operator in the coarse high-frequency subbands of each decomposition level, respectively. The experiment result improves our algorithm is efficient.
