Bilinear[in] | src | Source tensor info. Data types supported: QASYMM8/QASYMM8_SIGNED/U8/S8/S16/F16/F32. |
[in] | dx | Distance x tensor info. Pixel's distance between the X real coordinate and the smallest X following integer. Data type supported: F32 |
[in] | dy | Distance y tensor info. Pixel's distance between the Y real coordinate and the smallest Y following integer. Data type supported: F32 |
[in] | offsets | Offset tensor info. Offset to access the pixel with NEAREST interpolation or the top-left pixel with BILINEAR interpolation in the input tensor. Data type supported: S32. |
[out] | dst | Destination tensor info. Data types supported: Same as input . All but the lowest two dimensions must be the same size as in the input tensor, i.e. scaling is only performed within the XY-plane. |
[in] | info | ScaleKernelInfo to use for configuration |
