摘要
本文讨论主动图像声纳的图像结果显示问题,主要介绍一种基于快速小波分形插值的实时声纳图像缩放算法。并通过对合成孔径声纳图像数据进行算法比较,发现此算法比通用的图像插值算法,如双线性插值和双三次样条插值等,具有更好的性能。由于可以分块并行实现,因此本算法易于应用于实时图像声纳工程中。
A new fast wavelet based fractal interpolation algorithm for the processed image by active image sonar is described. Comparing with the conventional algorithms, such as the bilinear interpolation and bicubic interpolation, this algorithm has better performance in image data reduction by displaying the real synthetic aperture sonar image. Because of its ability of localization and parallel computation, the proposed algorithm is easy to be applied into the real-time image sonar system.
