An effective improvement on 3D SPIHT

As an extension of 2D SPIHT, 3D SPIHT inherits the properties of 2D SPIHT, and is suited very well large for volume data compression such as video, medical images, and multispectral images. But it still contains a great deal of redundant search, having not fully improved coding speed. In order to solve this problem, the authors of this paper successfully proposed a fast search algorithm, which can be applied to improve the 3D SPIHT coding algorithm, greatly reducing redundant search and improving coding speed. Experiments also show that the improved 3D SPIHT is really faster than the original 3D SPIHT for image and video compression.
