We propose a design of self-powering room-wide power usage and crowd activity sensing that uses a single point of contact on a conductive surface of furniture or everyday objects such as metal frame of table or window, desktop PC case, rack, cabinet, and so on. We utilize these surfaces for energy scavenging from capacitive reactance and electromagnetic(More)
The authors propose an online image search engine based on local image keypoint matching with GPU support. State-of-the-art models are based on bag-of-visual-words, which is an analogy of textual search for visual search. In this work, thanks to the vector computation power of the GPU, the authors utilize real values of keypoint descriptors and realize(More)
