2D Tophat filter kernel.
The Tophat filter is an isotropic smoothing filter. It can produce artifacts when applied repeatedly on the same data.
Radius of the filter kernel.
- modestr, optional
- One of the following discretization modes:
- ‘center’ (default)
Discretize model by taking the value at the center of the bin.
Discretize model by performing a bilinear interpolation between the values at the corners of the bin.
Discretize model by taking the average on an oversampled grid.
Discretize model by integrating the model over the bin.
- factornumber, optional
Factor of oversampling. Default factor = 10.
