This paper describes about on-line underwater image gathering utilizing stationary sensor node and movable sensor node. We consider applying them to investigate the conditions of marine ecosystem around coral leaf at Okinawa, Japan. The framework of our proposed underwater image gathering system is introduced. Current developments on stationary and movable sensor node prototypes are also described...
A method of learning image bases from natural images is proposed in this paper. Natural image is decomposed into structure mode and non-structure mode by using Empirical Mode Decomposition (EMD) technique. The structure mode is made up of the first two Intrinsic Mode Functions (IMF) that represent the structure information of image. The other IMFs and residual image compose the non-structure mode...
