Patient monitoring via video and physiological data recording can now be performed outside hospitals. This procedure, usually performed in a prolonged manner, generates a considerable amount of data, which calls for efficient ways for archiving and transmission. In this work, we present a specialized system to code the video and the physiological data recorded from a patient, aiming at a reduced bandwidth...
Change detection is a useful tool to identify content changes in images. Its significance is found in the applications of video surveillance, editing, coding and analysis. In this work, we present another application of change detection to patient video monitoring, based on a novel approach in the discrete cosine transform (DCT) domain. This approach is built upon a statistical test on the difference...
This paper presents a method to synthesize multi-view video frames to facilitate coding and transmission of patient monitoring video. The synthesis is carried out in the DCT domain by means of interlacing. The synthesized video provides a higher video coding efficiency, better synchronization of the video streams from multiple cameras, as well as the improved data loss resilience and protection of...
Object-based video representation plays an important role in remote patient monitoring built on video coding and Internet transmission. This paper introduces an object-based video representation method using two novel change detection techniques, and presents a demo system built upon ConferenceXP, where three types of video objects are constructed by exploiting the features in patient monitoring video...
