Setup the kernel parameters.
[in] | input1 | Source image (gradient X). Data types supported: S16/S32 |
[in] | input2 | Source image (gradient Y). Data types supported: same as @ input1 |
[out] | output | Destination image (harris score). Data types supported: F32 |
[in] | norm_factor | Normalization factor to use accordingly with the gradient size (Must be different from 0) |
[in] | strength_thresh | Minimum threshold with which to eliminate Harris Corner scores (computed using the normalized Sobel kernel). |
[in] | sensitivity | Sensitivity threshold k from the Harris-Stephens equation |
[in] | border_undefined | True if the border mode is undefined. False if it's replicate or constant. |
