Martin Desruisseaux created SIS-494:
---------------------------------------
Summary: Implement bicubic interpolation on rasters
Key: SIS-494
URL: https://issues.apache.org/jira/browse/SIS-494
Project: Spatial Information Systems
Issue Type: Task
Components: Features
Affects Versions: 1.1
Reporter: Martin Desruisseaux
Attachments: BiCubicTest.java
The {{org.apache.sis.image.Interpolation}} interface has predefined constants for {{NEAREST}},
{{BILINEAR}} and {{LANCSOZ}}, but currently no {{BICUBIC}}. Bicubic interpolation algorithm
is [described on Wikipedia|https://en.wikipedia.org/wiki/Bicubic_interpolation]. A first implementation
attempt is done on on SIS {{feat/bicubic}} branch but is currently bugged. This branch should
be debugged and more tests added before merge.
Java Advanced Imaging (JAI) may be used as a reference implementation for checking the values.
Attached is a class that may be used as a starting point, but also needs debugging.
