Latest Patents

David holds a patent for a "Method and apparatus for fast signal convolution using separated-spline kernel." This invention presents a fast convolution method that is applicable to convolving a signal indicative of an n-dimensional pattern, where n is greater than or equal to two. The method utilizes a smooth kernel that can be approximated by a separated-spline kernel. Unlike traditional Fourier-based convolution methods, which require on the order of N log N arithmetic operations for a signal of length N, David's method requires only on the order of N arithmetic operations. This efficiency is particularly beneficial in applications requiring rapid signal processing.
