The image package is part of the octave-forge project.

Development

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.

Roadmap

The following are missing targets for the next minor release of the image package (version 2.4.0). Small bug fixes, build fixes, and regressions may still be released before in a patch release (next would be version 2.2.3).

  • add ellipse properties to regionprops (see bug #44100)
  • speed up regionprops for large images with many small objects (probably work around for loop with {{{1}}}
  • support passing bwconncomp output to regionprops (and then fix bwpropfilt to use that instead of a labeled image)
  • ND support on imfilter
  • check if normxcorr2 is Matlab compatible and investigate making use of fftconvn since it's likely to receive large input
  • investigate implementing the missing deconvolution functions (see patch #8571
  • fix imadjust for other image types (only works for double on the [0 1] range at the moment)
  • anything else that is done or submitted before the above are done

Different functions

  • 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 options

  • @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.

Contributing

  • 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.
