Merhaba,<\/p>\n

K\u00e2h kameradan k\u00e2h herhangi bir foto\u011fraf yahut resimden olsun farketmeksizin \u00fczerinde g\u00f6r\u00fcnt\u00fc i\u015fleme \u00e7al\u0131\u015fmas\u0131 yapt\u0131\u011f\u0131m\u0131z herhangi bir uygulamada, alg\u0131lanan g\u00f6r\u00fcnt\u00fcy\u00fc b\u00fct\u00fcnden \u00e7\u0131karmay\u0131 isteyebiliriz. Yani g\u00f6r\u00fcnt\u00fcy\u00fc kesip elde etmeyi isteyebiliriz. \u0130\u015fte bu i\u00e7eri\u011fimizde \u00f6rnek olarak face detection\/y\u00fcz alg\u0131lama i\u015flemi neticesinde, alg\u0131lanan y\u00fczleri ana resimden \u00e7\u0131karacak ve sadece ilgili objeyi elde edece\u011fiz.<\/p>\n

Peki bu i\u015flemi nas\u0131l yapaca\u011f\u0131z?<\/strong><\/em>
\nAsl\u0131nda yapaca\u011f\u0131m\u0131z i\u015flem \u00e7okta \u015fa\u015fal\u0131 bir u\u011fra\u015f gerektirmemektedir. EmguCV s\u0131n\u0131flar\u0131n\u0131 kullanarak elde etti\u011fimiz y\u00fcz\u00fcn zaten Rectangle bilgilerini elde edebilmekteyiz. Eee ayr\u0131\u015ft\u0131r\u0131lacak olan par\u00e7an\u0131n koordinat bilgileri ve y\u00fckseklik\/geni\u015flik \u00f6l\u00e7\u00fcleri belirli olaca\u011f\u0131ndan geriye o ilgili par\u00e7ay\u0131 resimden kesmek kalmaktad\u0131r.<\/p>\n

Tabi bu i\u015flemi yaparken kamera \u00fczerinde \u00e7al\u0131\u015faca\u011f\u0131m\u0131z i\u00e7in kullanaca\u011f\u0131m\u0131z teknolojiler; kameradan g\u00f6r\u00fcnt\u00fc elde etme ve bu g\u00f6r\u00fcnt\u00fcler \u00fczerinde gerekli face detection i\u015flemlerini EmguCV ile ger\u00e7ekle\u015ftirece\u011fiz. Lakin kesilmesi gereken par\u00e7ay\u0131 ise AForge.NET framework\u00fcn\u00fc kullanarak elde edece\u011fiz.<\/p>\n

Yani uzun laf\u0131n k\u0131sas\u0131 olay bir kesme i\u015fleminden ibaret olacakt\u0131r.<\/p>\n

As\u0131l konumuza girmeden hemen \u015furada kesme konusunda bir \u0131s\u0131nma turu yapabiliriz.<\/p>\n

\u0130\u015fte bu kadar basit. G\u00f6rd\u00fc\u011f\u00fcn\u00fcz \u00fczere elimizde hali haz\u0131rda bir resim ve o resimde kesilecek alan\u0131n Rectangle koordinatlar\u0131 bulunmas\u0131 bizim i\u00e7in amac\u0131m\u0131z do\u011frultusunda tam tam\u0131na yeterlidir. Dikkat ederseniz resmimiz static oldu\u011fu i\u00e7in sadece AForge.NET k\u00fct\u00fcphanesindeki Crop s\u0131n\u0131f\u0131n\u0131 kullanmam yeterli olmu\u015ftur. Ama biz kameradan elde edilen birden \u00e7ok g\u00f6r\u00fcnt\u00fc \u00fczerinde hem y\u00fcz alg\u0131lay\u0131p hemde alg\u0131lanan y\u00fcz \u00fczerinde bir kesim i\u015flemi yapaca\u011f\u0131m\u0131z i\u00e7in EmguCV ile AForge.NET’i bir b\u00fct\u00fcn olarak kullanaca\u011f\u0131z. Yukar\u0131 sat\u0131rlarda da bahsetti\u011fim gibi EmguCV gerekli kamera g\u00f6r\u00fcnt\u00fcs\u00fcn\u00fc elde edip, o g\u00f6r\u00fcnt\u00fc \u00fczerinde gerekli face datection i\u015flemlerini ger\u00e7ekle\u015ftirecek ve alg\u0131lad\u0131\u011f\u0131 y\u00fcz\u00fcn Rectangle koordinatlar\u0131yla beraber ilgili resmi bize getirecektir. Gerisi yukar\u0131daki kod blo\u011funda yapm\u0131\u015f oldu\u011fumuz i\u015flemle birebir ayn\u0131d\u0131r diyebilirim. Devreye AForge.NET girecek, ilgili y\u00fcz\u00fc Rectangle koordinatlar\u0131 arac\u0131l\u0131\u011f\u0131yla kesecek ve bize sunacakt\u0131r.<\/p>\n
