سابقه و هدف: در سال­ های اخیر روند رو به افزایش تخریب منابع آب، خاک محیط زیست اثر کاربرد بی رویه مواد شیمیایی موجب ترغیب پژوهشگران کشاورزی ارگانیک سال ­های شده است. با وجود همه اثرات مثبتی که ارتباط مصرف آلی بر روی ویژگی­ فیزیکی مطرح است، هنوز این رابطه نگرانی­ زیادی از نظر مسائل زیست­ محیطی، سلامت دارد. بسته منبع، اغلب دارای مقادیر نسبتا عناصر سنگین می باشند؛ بنابراین اندازه گیری دقیق میزان فل...

Face recognition is important in human identification. The biological recognition technique acts as a good method and broad applications in security areas. This work presents a method to improve the face recognition accuracy using a combination of Principal Component Analysis (PCA), and Wavelet Transform. Wavelet Transform is used to decompose the input image with different levels and rearrange...
