<div dir="ltr">Hello all,
<div><br></div>
<div>We're doing some fiddling with face detection APIs, and were
wondering if any of you had any strong feelings on APIs to choose
or avoid?</div>
<div><br></div>
<div>Things we're interested in:</div>
<div><br></div>
<div>• Option for straight up face <i><u>detection</u></i> [bool -
"there's a face in that image!"], rather than full-fat face
recognition ["that's Mary!"], or analysis ["Mary is happy!"]. We're
only interested in detection.</div>
<div><br></div>
<div>• Value for money.</div>
<div><br></div>
<div>• Ease of integration, documentation, and reliability.</div>
<div><br></div>
<div>Any experiences with an API, good or bad, would be greatly
appreciated.</div>
<div><br></div>
<div>Many thanks in advance,</div>
<div> </div>
