gaussian pyramid

基本解释

In this paper, a spread spectrum digital watermark based on Gaussian pyramid decomposition was proposed.
提出了一种基于高斯金字塔分解的数字图像扩频水印技术。
But the Gaussian Pyramid used in Itti's model smoothes the image and the object's shape at the same time.
改进后的高斯金字塔的高斯核窗口能根据图像的平坦状况，自适应地改变窗口的方向、大小和形状。
Experimental results of SAR/Optical images fusion are given, which show that the proposed methods can obtain better fusion performance than traditional Gaussian-Laplacian pyramid algorithm.
实验结果表明，改进后的算法比传统的高斯-拉普拉斯金字塔方法有更好的融合效果。
