Wavelet Toolbox™ provides apps and functions for the time-frequency analysis of signals and multiscale analysis of images. You can denoise and compress data, and detect anomalies, change-points, and transients. The toolbox enables data-centric artificial intelligence (AI) workflows by providing time-frequency transforms and automated feature extractions, including scattering transforms, continuous wavelet transforms (scalograms), Wigner-Ville distribution, and empirical mode decomposition. You can extract edges and oriented features from images using wavelet, wavelet packet, and shearlet transforms.
The apps let you interactively perform time-frequency analysis, signal denoising, or image analysis, and generate MATLAB® scripts to reproduce or automate your work.
You can generate C/C++ and CUDA® code from toolbox functions for embedded deployment.
