multibox_prior(data=None, sizes=_Null, ratios=_Null, clip=_Null, steps=_Null, offsets=_Null, out=None, name=None, **kwargs)

Generate prior(anchor) boxes from data, sizes and ratios.

  • data (ndarray) – Input data.

  • sizes (tuple of <float>, optional, default=[1]) – List of sizes of generated MultiBoxPriores.

  • ratios (tuple of <float>, optional, default=[1]) – List of aspect ratios of generated MultiBoxPriores.

  • clip (boolean, optional, default=0) – Whether to clip out-of-boundary boxes.

  • steps (tuple of <float>, optional, default=[-1,-1]) – Priorbox step across y and x, -1 for auto calculation.

  • offsets (tuple of <float>, optional, default=[0.5,0.5]) – Priorbox center offsets, y and x respectively

  • out (ndarray, optional) – The output ndarray to hold the result.


out – The output of this function.
