higherthansurrounding
Higherthansurrounding is a coined term used to describe a value that exceeds its surrounding values. It is not a widely recognized technical term; when encountered, it typically serves as a descriptive label for a local extremum or peak in a data set, function, or spatial field.
In mathematics, the concept corresponds to a strict local maximum: there exists a neighborhood around a point
Context defines the surrounding: the neighborhood can be defined by radius, a fixed-size window, a metric-based
Related concepts include local maximum, peak detection, prominence in topography, maxima in optimization, and non-maximum suppression
Because the term is not standardized, users should specify the neighborhood definition and comparison metric when
