Subject [jira] [Created] (SIS-494) Implement bicubic interpolation on rasters
Date Mon, 06 Apr 2020 17:22:00 GMT
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.
