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 ...

This project simulates the 3D attitude control of a quadcopter using PID controllers in MATLAB. The simulation numerically integrates the quadcopter’s nonlinear equations of motion using the ODE45 ...

Abstract: Remote sensing image dehazing is critical for restoring spectral fidelity in Earth observation tasks. While vision Transformers (ViTs) excel at global context modeling, preserving ...

Abstract: Digital cameras have become ubiquitous for amateur and professional applications. The raw images captured by digital sensors typically take the form of color filter array (CFA) mosaic images ...

Know what message you’re trying to communicate before you get down in the weeds. by Scott Berinato Not long ago, the ability to create smart data visualizations, or dataviz, was a nice-to-have skill.

Welcome to Smithsonian Open Access, where you can download, share, and reuse millions of the Smithsonian’s images—right now, without asking. With new platforms and tools, you have easier access to ...
