=== Roadmap === | |||
The following are missing targets for the next minor release of the image package (version 2.8.0). Small bug fixes, build fixes, and regressions may still be released before in a patch release (Version 2.6.X). | |||
* add ellipse properties to {{codeline|regionprops}} (see bug {{bug|44100}}) ([http://hg.code.sf.net/p/octave/image/rev/7cf22a478792 done]) | |||
* speed up {{codeline|regionprops}} for large images with many small objects (probably work around for loop with labeled == labelid) | |||
* support passing {{codeline|bwconncomp}} output to {{codeline|regionprops}} (and then fix {{codeline|bwpropfilt}} to use that instead of a labeled image) | |||
* ND support on {{codeline|imfilter}} | |||
* check if {{codeline|normxcorr2}} is Matlab compatible and investigate making use of {{codeline|fftconvn}} since it's likely to receive large input | |||
* investigate implementing the missing deconvolution functions (see patch {{patch|8571}}) | |||
* anything else that is done or submitted before the above are done | |||
