 Multidimensional signal processing

Multidimensional signal processing refers to the analysis and manipulation of signals that vary over more than one dimension. While traditional signal processing typically deals with one-dimensional signals, such as audio waveforms or time series data, multidimensional signal processing expands this concept to include signals that have multiple dimensions. The most common examples include: 1. **Two-Dimensional Signals**: These are often images or video frames, where each pixel represents a signal value.
