Biz sizlar bilan “OpenCV<\/strong>” va Python bilan inson yuzini aniqlash dasturini tuzishni o’rganamiz. Buning uchun bizga “OpenCV<\/strong>” kutubxonasi va inson yuzi aks etgan rasm kerak bo’ladi.<\/p>\n\n\n\n

Kutubxonani o’rnatish uchun terminalga quyidagi buyruqni kiriting:<\/p>\n\n\n\n

Kutubxona o’rnatilganda so’ng kerakli rasmni yuklab oling. Qandayligini ahamiyati yo’q. Muhumi unda inson yuzi tasvirlangan bo’lishi kerak.
Men “Steve Jobs<\/strong>” va uning do’stlari birgalikda tushgan rasmidan foydalanaman.

Rasmda uch inson yuzi tasvirlangan va biz ularning barchasini dasturda aniqlashimiz kerak. <\/p>\n\n\n\n
import cv2
yuzning_shakli = cv2.CascadeClassifier(cv2.data.haarcascades + “haarcascade_frontalface_default.xml”)<\/p>\n\n\n\n
Opencv kutubxonasini cv2 orqali import qilamiz.”yuzning_shakli<\/strong>” nomli o’zgaruvchiga kutubxonamizda yuzning tuzulishi haqidagi ma’lumotlarni yuklaymiz. Biz kiritgan parametrlarga asoslanib dasturimiz endi inson yuzini aniqlay oladi.<\/p>\n\n\n\n

Keyingi qadam.
Dasturimizga kerakli rasmni yuklab olamiz va ranglarni belgilab olamiz.
Yuklangan rasmni  “BGR<\/strong>” va “GRAY<\/strong>” ranglari orqali aks etadi.”BGR<\/strong>” bu “Blue, Green, Red<\/strong>” ,”GRAY<\/strong>” esa “Green, Red, Azure, Yellow<\/strong>” so’zlarining qisqartmasi.<\/p>\n\n\n\n
