The H.264/AVC standard provides high compression efficiency at the cost of increased computational complexity. As a consequence, dedicated hardware circuits are typically required for its most computationally intensive parts, such as the transform coding block that must support multiple transform operations: the 4× 4 forward and inverse integer DCT and the 4×4 and 2×2 Hadamard transforms. In th...

background: electromyographic (emg) signal decomposition is the process by which an emg signal is decomposed into its constituent motor unit potential trains (mupts). a major step in emg decomposition is feature extraction in which each detected motor unit potential (mup) is represented by a feature vector. as with any other pattern recognition system, feature extraction has a significant impac...

In this paper, we give a new vanishing point detection algorithm, called the normalized unit sphere. By normalizing homogeneous coordinates in the original image space, we transform image points onto a normalized unit sphere. Further, we transform straight lines in image space into circles on normalized unit sphere. As a result, the vanishing point detection is implemented by searching the inte...
