Struct opencv::gapi::GMat

pub struct GMat { /* private fields */ }

GMat class represents image or tensor data in the graph.

GMat doesn’t store any data itself, instead it describes a functional relationship between operations consuming and producing GMat objects.

GMat is a virtual counterpart of Mat and UMat, but it doesn’t mean G-API use Mat or UMat objects internally to represent GMat objects – the internal data representation may be backend-specific or optimized out at all.

Implementations

impl GMat

pub fn default() -> Result<GMat>

Constructs an empty GMat

Normally, empty G-API data objects denote a starting point of the graph. When an empty GMat is assigned to a result of some operation, it obtains a functional link to this operation (and is not empty anymore).
