Applications
Description
This operation is a simplified, fast in computation, version of SmoothImage_Gauss, with predefined kernel and simplified ROI handling.
Kernel used in operation can be chosen by inKernel parameter:
- Box_3x3: 3 by 3 pixels kernel with StdDev ≈ 0.85 of following form:
- Box_5x5: 5 by 5 pixels kernel with StdDev ≈ 1.1 of following form:
- Box_7x7: 7 by 7 pixels kernel with StdDev ≈ 1.7 of following form:
- Box_9x9: 9 by 9 pixels kernel with StdDev ≈ 2.0 of following form:
- Box_11x11: 11 by 11 pixels kernel with StdDev ≈ 2.2 of following form:
Hints
- Select kernel size by setting the inKernel input.
