Community driven content discussing all aspects of software development from DevOps to design patterns. Ready to develop your first AWS Lambda function in Python? It really couldn’t be easier. The AWS ...

A windowed sinc function can implement a low-pass filter, and a two-dimensional convolutional filter can blur or sharpen images. In part 3 of this series, we introduced a low-pass filter based on the ...

This script contains my origianl filter function which was retired on 23/09/2016 as it uses convolution in the time domain to apply the filter which makes it slow and particularly inefficient with ...

The Fn key is short for function – this particular key allows PC users to access the second assignment of a key. It is normally found at the bottom left corner. The Function keys (F1, F2, etc) are ...

Uses Toeplitz convolutional matrix multiplication to perform sparse convolution. This allows for extremely fast convolution when: The kernel is small (<= 100x100) The input array is sparse (<= 1% ...

ABSTRACT: The convolution of two rational transfer functions is also rational, but a formula for the convolution has never been derived. This paper introduces a formula for the convolution of two ...

Abstract: This paper investigates the possibility of performing the convolution function in the frequency domain using the fast Fourier transform. The paper presents the proposed structure of the ...
