resize(_:sizeTensor:scaleOffsetTensor:mode:layout:name:)

Resamples input images to given size using the provided scale and offset. Destination indices are computed using

Declaration

func resize(_ imagesTensor: MPSGraphTensor, sizeTensor size: MPSGraphTensor, scaleOffsetTensor scaleOffset: MPSGraphTensor, mode: MPSGraphResizeMode, layout: MPSGraphTensorNamedDataLayout, name: String?) -> MPSGraphTensor

Parameters

  • imagesTensor:

    Tensor containing input images.

  • size:

    1D Int32 or Int64 tensor. A 2-element shape as [newHeight, newWidth]

  • scaleOffset:

    1D float tensor. A 4-element shape as [scaleY, scaleX, offsetY, offsetX]

  • mode:

    The resampling mode to use. If nearest sampling is specifed, RoundPreferCeil mode will be used.

  • layout:

    Specifies what layout the provided tensor is in. The returned tensor will follow the same layout. Valid layouts are NHWC, NCHW, HWC, CHW, and HW.

  • name:

    The name for the operation.

Return Value

A valid MPSGraphTensor object

Discussion

dst_indices = (src_indicesscale) + offset

For most use cases passing the scale and offset directly is unnecessary, and it is preferable to use the API specifying centerResult and alignCorners.
