The image package is part of the Octave Forge project. See its homepage for the latest release.

DevelopmentEdit

Follows an incomplete list of stuff missing in the image package to be matlab compatible. Bugs are not listed here, search and report them on the bug tracker instead.

Missing functionsEdit

this entire section is about the current development version. If a Matlab function is missing from the list and does not appear on the current release of the package, confirm that is also missing in the development sources before adding it.

Different functionsEdit

  • with version 2014a, Matlab introduced a new function imtranslate. This function was part of Octave's package since 2002 but Matlab version is completely different. It needs to be rewritten for Matlab compatibility.

Missing optionsEdit

  • @strel
    • missing SE decomposition for the diamond shape
    • approximation argument for the ball and disk shapes are not implemented
    • the translate method is not yet implemented
  • blockproc
    • The name-value input arguments have not yet been implemented.
  • colfilt
    • the option to split the image in smaller blocks before performing the im2col and filtering is ignored. Since that option only allows to use less memory and has no effect on the output is only important for sliding filtering with big blocks size.
  • impixel
    • interactive selection of points (less than 2 input arguments) is not yet implemented. Ability to create such UIs needs to be implemented in Octave core first.
  • imcrop
    • messing around with alternative coordinate systems (XData and YData) are not yet implemented.
  • imwrap
    • no supports for SmoothEdges option
  • hough
    • no RhoResolution option

ContributingEdit

  • It'd help to group the missing functions above, as per [1] (similar to what was done in the signal package wiki page); please keep the original alphabetical list intact.
