A new FFT architecture for real-time implementation of large FFTs is presented. The architecture supports both, highthroughput and variable-length processing capabilities. The imp...
Histogram Intersection (HI) kernel has been recently introduced for image recognition tasks. The HI kernel is proved to be positive definite and thus can be used in Support Vector ...
