Mine disaster occurred, underground power and communications systems were severely damaged, and cause great difficulties for the relief effort. Therefore, it has some practical value to design a suitable video network which is applied to underground. In this paper, we propose a simple scheme of wireless multimedia sensor network for mine rescue that combines the multiple descriptions transform coding (MDTC) method with the discrete wavelet transform (DWT), and propose the active images detection algorithm which can separate the active images from the background. Simulation result shows that this scheme has a good performance in video compression and reliable transmission.
