碩士 === 國立交通大學 === 資訊學院資訊學程 === 104 === Nighttime surveillance has been widely used in several places nowadays, and Multi-Intensity Infrared Illuminator has been proposed to solve the under-exposure and over-exposure problems at long and short distance between the camera and target objects, which is caused by fixed brightness. However, the character of multi-intensity will result in low efficiency in video coding. In this thesis, we will try to perform video coding in a more efficient way toward the videos recorded by camera equipped with Multi-Intensity Infrared Illuminator. HEVC (High Efficiency Video Coding), which is the new generation of video coding standard, is adopted for it for its outstanding compression performance. First, we directly send the original video as a single view into HEVC to do video coding, and set the coding performance as baseline. Next we separate the original video into some brightness-fixed videos according to the different channel of Multi-Intensity Infrared Illuminator, and send them into Multi-view and 3D mode of HEVC to do the video coding. Because the video after separating are suitable for the inter-view prediction of Multi-view and 3D mode of HEVC, finally we will get better performance compared to single view case. Besides, we will discuss the strategies and how to improve the coding efficiency and in several different scenes.
