Four-Dimensional Wavelet Compression of 4-D Medical Images Using Scalable 4-D SBHP
2007 Data Compression Conference (DCC'07), 2007This paper proposes a low-complexity wavelet-based method for progressive lossy-to-lossless compression of four dimensional (4-D) medical images. The subband block hierarchal partitioning (SBHP) algorithm is modified and extended to four dimensions, and applied to every code block independently.

Actions representation in a 4-D space
International Journal of Man-Machine Studies, 1991In this paper a frame-based model is presented for the representation of actions in four dimensions (space+time). This model, called Action Net, allows the composition of different actions descriptions and the representations at different levels of detail: an action is represented by a tree of frames which degenerates in a single frame at the lowest ...
