The filter_utils module contains the free function apply_condition_filter() shared between the legacy RasterGridEvaluator and the new RasterGridEvaluatorPP to guarantee byte-identical conditional filtering across both code paths.

Functions

apply_condition_filter(val, cond, mask)

Apply the given conditional filter to the given mask.
src.eval.raster.filter_utils.apply_condition_filter(val, cond, mask)

Apply the given conditional filter to the given mask.

The body of this function is a verbatim copy of the legacy RasterGridEvaluator.filter() static method so that the legacy and the PP evaluators share byte-identical filter semantics. The exception messages, the recognized condition types, and the action handling are preserved as-is.

Parameters:

  • val (np.ndarray) – The vector of values considered by the filter.

  • cond (dict) – The condition specification governing the filter. See the conditions argument of PointCloudSampler.filter_support_points() for further details.

  • mask (np.ndarray) – The boolean mask representing the composition of conditions that defines the full filter, at its current state.

Returns:

The updated boolean filter mask.

Return type:

np.ndarray
