In medicine, spectral features are used to analyze brain waves (EEG) for tasks like sleep staging. 2. Film and Fiction (The Ghostly)
This is the distribution of power over a frequency range, often described using Power Spectral Density (PSD) . It helps engineers see where the "strength" of a signal lies. Light and Imaging: Spectral
In technical contexts, "spectral" refers to the distribution of a signal's properties, like energy or power, across different frequencies. In medicine, spectral features are used to analyze
The ability of a sensor (like a camera) to distinguish between different wavelengths of light, such as infrared or ultraviolet, beyond what the human eye can see. like energy or power
