Merhaba,<\/p>\n

Son zamanlarda g\u00f6r\u00fcnt\u00fc i\u015fleme \u00fczerine \u00e7al\u0131\u015fmalarda bulunmaktay\u0131m. Tabi bu \u00e7al\u0131\u015fmalar\u0131mda yo\u011funluk olarak AForge.NET, EmguCV ve Accord.NET frameworklerini kullanmakta ve bu teknolojilere ait t\u00fcm ke\u015fiflerimi tek tek siz de\u011ferli okuyucular\u0131ma sunabilmenin tela\u015fesiyle makaleler olu\u015fturmaktay\u0131m. Her konuda oldu\u011fu gibi \u015fuana kadar g\u00f6r\u00fcnt\u00fc i\u015fleme \u00fczerine yapt\u0131\u011f\u0131m \u00e7al\u0131\u015fmalar o kadar lezzet ve haz verici sonu\u00e7lar vermi\u015ftir ki zamanla bu \u00e7al\u0131\u015fmalar \u00fczerine i\u00e7erikler olu\u015fturduk\u00e7a ne demek istedi\u011fimi sizlerde anlayacaks\u0131n\u0131z. Misal bu yaz\u0131m\u0131zda; bu e\u011flenceli \u00e7al\u0131\u015fmalardan netice elde etti\u011fim bir konu olan ve C# ile bir g\u00f6r\u00fcnt\u00fc \u00fczerinde y\u00fcz alg\u0131lama olarak nitelendirilen Face Detection olay\u0131n\u0131n Accord.NET framework\u00fcn\u00fc kullanarak nas\u0131l ger\u00e7ekle\u015ftirildi\u011fini ele alaca\u011f\u0131z.<\/p>\n

\u0130\u00e7eri\u011fe ba\u015flamadan belirtmek istedi\u011fim m\u00fchim bir nokta vard\u0131r. Birazdan da g\u00f6rece\u011finiz \u00fczere Face Detection uygulamas\u0131n\u0131 Accord.NET ile basit ve h\u0131zl\u0131 bir \u015fekilde ger\u00e7ekle\u015ftirebilece\u011fiz. Halbuki bu uygulama taraf\u0131m\u0131zdan bir ba\u015flang\u0131\u00e7 seviyesinde kabul edilecektir ve zamanla ayn\u0131 i\u015fi daha y\u00fcksek teknolojide nas\u0131l yapabiliriz konusunu ele al\u0131p de\u011ferlendirece\u011fiz. Bu konuda EmguCV ve di\u011fer teknolojiler \u00fczerinden ara\u015ft\u0131rmalar\u0131ma devam etmekte oldu\u011fumu bilmenizi isterim.<\/p>\n

\u015eimdi makalemize d\u00f6nelim…<\/p>\n

Makale s\u00fcrecinde, g\u00f6r\u00fcnt\u00fc a\u00e7\u0131s\u0131ndan web kameradan beslenece\u011fimiz i\u00e7in AForge.NET’in kameraya ba\u011flanma i\u015flevini g\u00f6ren s\u0131n\u0131flar\u0131ndan yararlanaca\u011f\u0131m\u0131z\u0131 bilmenizi isterim. Bunlar\u0131n yan\u0131nda s\u00fcreci takip etmek istiyorsan\u0131z bir adet Windows Form projesi a\u00e7\u0131p, form \u00fczerine bir adet PictureBox nesnesi eklemeniz gayet yeterli olacakt\u0131r.<\/p>\n

\u0130lk olarak Accord.NET k\u00fct\u00fcphanelerini projemize entegre ederek ba\u015flayal\u0131m. Bu i\u015flem i\u00e7in Nuget penceresini a\u015fa\u011f\u0131daki gibi kullanabiliriz.

Yukar\u0131da g\u00f6r\u00fcld\u00fc\u011f\u00fc \u00fczere Accord.NET k\u00fct\u00fcphanesini projemize entegre ediyoruz. Ayr\u0131ca kamera i\u015flemleri i\u00e7in AForge.NET k\u00fct\u00fcphanesini kullanaca\u011f\u0131m\u0131z i\u00e7in de bu adresteki<\/a> belirtmi\u015f oldu\u011fum t\u00fcm k\u00fct\u00fcphaneleri projenize dahil etmeyi unutmay\u0131n.<\/p>\n

\u015eimdi s\u0131ra geldi kod yazmaya.<\/p>\n

\u00d6ncelikle sistemdeki dahili kameraya ba\u011flan\u0131p g\u00f6r\u00fcnt\u00fc elde edelim.<\/p>\n
