Make it a member of your class. This way, it will be accessible from within any of your class member function.

For instance making processedimage (or imagedata) member of the CAutoDetHumanDlg class. :)

If the data belongs to the CAutoDetHumanDlg class, it is accessible by any of its members. Just use it.

Both OnSmoothImg() and OnCalculateFeatures() access the data in the same way.

Get a book and study it to start with. There are many but something like this[^] is a good place to start.
