Initialise the kernel's sources, destination and border mode.
[in] | magnitude | Source tensor - Magnitude. Data type supported: U16/U32. |
[in] | phase | Source tensor - Quantized phase. Data type supported: U8. |
[out] | output | Output tensor. Data type supported: U8. It will be filled with 0 for "no edge", 127 for "maybe", 255 for "edge" |
[in] | upper_thr | Upper threshold used for the hysteresis |
[in] | lower_thr | Lower threshold used for the hysteresis |
[in] | border_undefined | True if the border mode is undefined. False if it's replicate or constant. |
