用于生成5个级别的高斯金字塔和拉普拉斯金字塔的Python代码,并将这些图像连接起来以显示金字塔。 当前,在OpenCV中没有可用的功能以这种方式显示金字塔图像(尽管可在MATLAB中使用)。 可能不是最优雅的方法,但是可以完成工作。 可以轻松改进。 该代码还为图像生成2D ...
Pyramid, or pyramid representation, is a type of multi-scale signal representation developed by the computer vision, image processing and signal processing communities, in which a signal or an image is subject to repeated smoothing and subsampling. Pyram
