pub struct MediaFrame { /* private fields */ }
Expand description
cv::MediaFrame class represents an image/media frame obtained from an external source.
cv::MediaFrame represents image data as specified in cv::MediaFormat. cv::MediaFrame is designed to be a thin wrapper over some external memory of buffer; the class itself provides an uniform interface over such types of memory. cv::MediaFrame wraps data from a camera driver or from a media codec and provides an abstraction layer over this memory to G-API. MediaFrame defines a compact interface to access and manage the underlying data; the implementation is fully defined by the associated Adapter (which is usually user-defined).

Helper function to call OpenCV functions that allow in-place modification of a
Mat
or another similar object. By passing
a mutable reference to the Mat
to this function your closure will get called with the read reference and a write references
to the same Mat
. This is unsafe in a general case as it leads to having non-exclusive mutable access to the internal data,
but it can be useful for some performance sensitive operations. One example of an OpenCV function that allows such in-place
modification is imgproc::threshold
. Read more
