Following advice, I updated to version 7.0 for mac, which I realize uses a different algorithm for face recognition. As I did not want to have to retag hundreds of images, I did not delete tags made under the earlier version, but rescanned a few folders with the setting on 'scan again and merge results' and 'recognize faces'. The new scan, however, placed all newly-scanned files under 'unknown'. I retagged a large number of faces, mostly showing my wife, and tried a further scan on the same settings (but using the scan command under tools>maintenance) expecting that it might now learn from these newly-tagged files and recognize the faces of my wife at least. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Unfortunately, the program crashed before completing the scan, but not before adding a few thousand new faces. However, once again almost all of these, including my wife's face, were placed under 'unknown' rather than being recognized; the few placed under 'unconfirmed' were wrongly identified. Rescanning individual files had no effect. This makes me wonder if the recognition feature is working (or if I am doing something wrong).</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Further, under both 6,4 and 7.0 the scan is failing to detect many faces in photos with more than one person even though these are (as far as I can tell) every bit as large and clearly visible as the ones it does detect. I tried rescanning the same files repeatedly with different sensitivity settings, from 0-100%, but the results were always the same. Is there anything I can do about this short of manually adding faces to thousands of files?</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Thanks for assisting me with this.</div><div><br></div><div class="ydp95005011signature">Ronald Orenstein<br>1825 Shady Creek Court<br>Mississauga, ON L5L 3W2<br>Canada<br>ronorenstein.blogspot.com<br>ronorensteinwriter.blogspot.com</div></div>
