چکیده

در این مقاله روشی چالاک سریع و با دقت بالا برای تشخیص تصویر چهره انسانی در تصاویر رنگی ارایه می‌شود که بیشتر تمرکز آن در یادگیری جزیی برای کاربرد در ملیت‌های خاص و تصاویر پوستی همگون است. روش پیشنهادی به‌دلیل استفاده از مدل پوست در تصاویر رنگی و الگوی چهره، متفاوت با روش‌های دیگر است و نیازی به آموزش و یادگیری به روش‌های سنتی را ندارد. مستقل از وضعیت نورپردازی، رنگ پس‌زمینه، موقعیت چهره، زاویه چرخش حول محورصورت، اندازه تصویر، وضوح تصویر و شرایط عکس‌برداری است. ضمناً تصاویر دارای ریش، عینک، با حالت خنده و بدون محدودیت تعداد چهره‌های موجود نیز آشکار می‌سازد.نتایج آزمایش‌های تجربی بر روی نمونه‌های تصویر رنگی استاندارد و خاص حاوی چهره‌های متعدد و متفاوت انسانی با پس‌زمینه پیچیده، تحت شرایط مختلف محیطی با همزمانی وجود چندین چهره در یک تصویر، نشان می‌دهد که سیستم از دقت 97% الی 98% با جامعیت و مانعیت خوب در شرایط مختلف برخوردار است.
