Parameters

rows  UInt16

Number of rows in the image

cols  UInt16

Number of cols in the image

pixelType  PixelType

PixelType of the image

stride  Int32

Number of bytes each row occupies

data  IntPtr

Pointer to image data. This will be pinned on the heap.

order  ChannelOrder

ChannelOrder of the image

timestamp_millisec  Double

The timestamp in milliseconds of this video frame.

Accurate DFX predictions require a consistent and accurate timestamp for the video frames. This is easily achievable when processing offline videos, but will require some effort for processing real-time camera feeds to ensure the frames maintain a consistent inter-frame interval.

number  UInt32

The video frame number within the video sequence.

Frame numbers are expected to be sequentially provided for a measurement and the number of sequential frames must be sufficient for the study measurement requirements to be fulfilled. Since multiple measurements can be performed on a video sequence, the frame number helps identify positioning within a video and if a frame is lost.
