I am a software developer specialized in Compilers, Security, and Graphics. I recently saw Project Hail Mary, and it was amaze amaze amaze! So now, I'm reading the book. In the movie, Grace translates ...

网上有些博主写的信号处理文章也不错，但是我觉得缺少了信号与系统的数学之美，而且整体给的说服力也不够。（那我就准备启动重写计划） 当采样点数从 增加到 、 时，正弦信号峰值基本不变，而频域每个 bin 里的噪声功率大约每增加 10 倍点数下降 10 dB。

I have been conducting various video analyses using MediaPipe and Python. A book I read recently described a method for calculating heart rate from color changes in the face or hands within a video, ...

[导读]在生物医学信号处理领域，MATLAB凭借其强大的快速傅里叶变换(FFT)功能，成为分析心电信号(ECG)和脑电信号(EEG)频域特性的核心工具。通过FFT算法，研究者能够将时域信号转换为频域分布，精准识别信号中的关键频率成分，为疾病诊断和生理机制研究提供 ...

Abstract: Organizations are increasingly exploring the integration of Generative AI (GenAI) into software engineering workflows. Despite the promise of improved productivity, the challenge of ...

Abstract: To enhance the fault tolerance of the fast fourier transform (FFT) processor in the presence of single event effect (SEE), this paper proposes a multistage scalable reduced precision ...

A minimal "getting start" tutorial is available at https://pynufft.readthedocs.io/en/latest/index.html. This package reimplements the min-max interpolator (Fessler ...

mpi4py-fft is a Python package for computing Fast Fourier Transforms (FFTs). Large arrays are distributed and communications are handled under the hood by MPI for Python (mpi4py). To distribute large ...
