In order to reduce the algorithm operation time,we propose a novel segmentation algorithm of marrow cell images based on the mathematical morphological pyramid and the watershed segmentation.

In order to eliminate the noise and preserve the fine structure features of the scanned image, a method of scanned image denoising based on mathematical morphological pyramid is proposed, which is used to decompose an image level-wise and the detail information is filtered in different resolution spaces, finally restructure a cleaned image with the detail information processed.

A fusion method is introduced which is based on morphological pyramid decomposition,and applied to ikonos images.

An algorithm is proposed in the paper to extract video object from dynamic scene based on motion estimation and the graph pyramid.

The imaging pyramid set forth by Wu Xuan, consisting of image, individual image and unique image, has an explored significance in the aspect of researching the art value of works.
