| Abstract: | In order to obtain better monitoring effect under low luminance environment, based on the human visual system, the image information was enhanced by compensating the human visual contrast resolution. Meanwhile, an embedded monitoring system was constructed with the combination of ARM11 and LINUX, so the coding efficiency was greatly improved by the hardware coding. Then the encoded H264 stream was transported with RTP package. Tests results show that the system can realize real-time monitoring under low luminance as well as obtain enhanced video images. |
