Initialise the kernel's inputs, output and HOG's metadata.
[in] | input_magnitude | Input tensor which stores the magnitude of the gradient for each pixel. Data type supported: S16. |
[in] | input_phase | Input tensor which stores the phase of the gradient for each pixel. Data type supported: U8 |
[out] | output | Output tensor which stores the local HOG for each cell. Data type supported: F32. Number of channels supported: equal to the number of histogram bins per cell |
[in] | hog_info | HOG's metadata |
