This paper presents a novel people counting system for an environment in which a stationary camera can count the number of people watching a TV-wall advertisement or an electronic billboard without counting the repetitions in video streams in real time. The people actually watching an advertisement are identified via frontal face detection techniques. To count the number of people precisely, a complementary...
A UWB BPF with a 5-GHz notched band and an improved upper stopband has been proposed and designed. By properly locating the first five resonant modes of the TSSIR, we have successfully implemented a five-transmission-pole UWB BPF. The notched band was created by the embedded lambda/4 open stubs. The upper stopband rejection has been effectively enhanced by locating around the first spurious resonant...
Blocking effect is the major drawback in DCT-based (discrete cosine transformation) codecs at low bit-rates. In this paper, a post-processing filter is proposed in DCT frequency domain. The proposed algorithm uses a shift block within four adjacent DCT blocks to reduce computational complexity. By slightly modifying several DCT coefficients in the shift block, the artifacts that result from quantization...
