Stereo Image Reduce to Selection ================================ Removes unselected frames from a stereo shared image set in place. Input ----- One stereo shared image set with a partial frame selection — at least one frame must be selected and at least one frame must be unselected. Output ------ The input stereo shared image set is modified: unselected left and right frames are removed. After the run, all remaining frames are selected. Description ----------- This is the stereo counterpart of the Base **Reduce to Selection** algorithm. Unlike **Stereo Image Extract Selection**, no new data object is created; the original stereo set is shortened to the current selection. Typical workflow: define a frame range in the :ref:`selection widget`, then choose *Selection Operations* → *Reduce to Selection*.
