gaussian pyramid

基本解释

In this paper, a spread spectrum digital watermark based on Gaussian pyramid decomposition was proposed.
提出了一種基於高斯金字塔分解的數字圖像擴頻水印技術。
But the Gaussian Pyramid used in Itti's model smoothes the image and the object's shape at the same time.
改進後的高斯金字塔的高斯核窗口能根據圖像的平坦狀況，自適應地改變窗口的方曏、大小和形狀。
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.
實騐結果表明，改進後的算法比傳統的高斯-拉普拉斯金字塔方法有更好的融郃傚果。
