An Extended Local Binary Pattern for Gender Classification
… accuracy. In this regard, we proposed a novel local binary descriptor capable of extracting more informative and discriminative local features for the purpose of gender classification. We have evaluated our approach on the standard FERET and CAS-PEAL databases and our experiments show that the …

Design And Implementation Of Fast Motion Estimation In Modern Video Compression On GPU
… with a brand new method which based on lbp (local binary pattern) code. Our new method first encodes the original video frames into lbp code and then compares the blocks only using the lbp code. Our algorithm reduces the amount of computation significantly by avoiding many pixel by pixel …

Surface myoelectric signal analysis and enhancement for improved prosthesis control
… For this, the behaviour of One-Dimensional Local Binary Pattern histograms were used to identify the presence of myoelectric activity in recorded signals that originated from electrode sensors on the surface of the skin. This technique was compared against two other activity detection …

SigSpace – Class-Based Feature Representation for Scalable and Distributed Machine Learning
… MNIST with image features like Pixels, SIFT, and Local Binary Pattern. Secondly, SigSpace was evaluated in the audio classification context with imperative audio features extracted from real-time audio datasets. The SigSpace system was implanted using a Big data analytics tool, Apache Spark(MLLib) …
