In this paper, we leverage RFID technology to label different objects withRFID tags, so as to realize the vision of "show me what I see from the augmented reality system". We deploy additional RFID antennas to the COTS depth camera and propose a continuous scanning-based scheme to scan the objects, i.e., the system continuously rotates and samples the depth of field and RF-signals from these...
With the rapid proliferation of RFID technologies, RFID has been introduced into applications such as inventory and sampling inspection. Conventionally, in RFID systems, the reader usually identifies all the RFID tags in the interrogation region with the maximum power. However, some applications may only need to identify the tags in a specified area, which is usually smaller than the reader’s default...
In this paper we describe a framework to improve the detection of ball hit events in tennis games by combining audio and visual information. Detection of the presence and timing of these events is crucial for the understanding of the game. However, neither modality on its own gives satisfactory results: audio information is often corrupted by noise and also suffers from acoustic mismatch between the...
The color interpolation method of Bayer CFA used in most digital cameras plays an important role in imaging system. In Bayer pattern, the green components are the twice as much as red or blue and contain more image information, which can be used to compensate the interpolations of red and blue. Due to the high correlation among the three color channels, color mutation is prevented by the fixed color...
