Purpose:
Determine Gaussian 2D digital filters with integer numbers and sums=2^n , n is integer. The filters are designed especially for FPGA. Divisions may be replaced by much faster shift operations.
Features:
Create 2D Gaussian filters with following properties:
- Expose full digital filters that have a sum of 2n , with n as integer number.
- Create also floating numbers filter.
- Determine optimal filter by spectrum.
- Plot spectral properties.
- See results on artificial images.
