- Abstract
According to the problem of image blurring with noise in SAR imaging, an adaptive enhancement algorithm for SAR image which combines with the noise visibility function is proposed.This algorithm realizes the adaptive processing of the detail layer,combined with the visual characteristics of human eyes and the noise visibility function,based on the image layering. The processing of each pixel in the base layer and the detail layer is calculated in parallel according to the characteristics of GPU architecture and memory, and the parallel optimization design of the algorithm is completed.The simulation results show that this algorithm can improve the image quality effectively,and at the same time,enhance the real-time performance of SAR image enhancement by making full use of GPU parallel computing ability.
