Rerun

Image

A monochrome or color image.

The order of dimensions in the underlying components.TensorData follows the typical row-major, interleaved-pixel image format. Additionally, Rerun orders the datatypes.TensorDimensions within the shape description from outer-most to inner-most.

As such, the shape of the components.TensorData must be mappable to:

  • A HxW tensor, treated as a grayscale image.
  • A HxWx3 tensor, treated as an RGB image.
  • A HxWx4 tensor, treated as an RGBA image.

Leading and trailing unit-dimensions are ignored, so that 1x480x640x3x1 is treated as a 480x640x3 RGB image.

Rerun also supports compressed image encoded as JPEG, N12, and YUY2. Using these formats can save a lot of bandwidth and memory.
