A simple C++ example of performing a one-dimensional discrete convolution of real vectors using the Fast Fourier Transform (FFT) as implemented in the FFTW 3 library. This code is a simple and direct ...

This project demonstrates discrete-time convolution using several approaches implemented in MATLAB. The goal of the project is to build an intuitive understanding of convolution in the time domain and ...

What on Earth is a discrete convolution? You might have seen the mathematical formula, but there is some good intuition that sadly isn’t explored much from an academic perspective. Here are the three ...

Abstract: In this paper, a hybrid Discrete Singular Convolution - Finite Difference Frequency Domain (DSCFD) method with high-order accuracy is proposed. The proposed method discretizes the curl ...

One of my favorite lectures in DSP is 2D convolution. If you love visualizing concepts like I do, this video is a great way to see both 2D convolution and its application in image processing. In this ...

Abstract: In this article, a hybrid discrete singular convolution-finite-difference frequency domain (DSCFD) method with high-order accuracy is proposed. The proposed method discretizes the curl ...

Crowd counting is considered a challenging issue in computer vision. One of the most critical challenges in crowd counting is considering the impact of scale variations. Compared with other methods, ...
