PyTorch’ta RandomInvert: G\u00f6r\u00fcnt\u00fc \u0130\u015flemede Rastgele Ters \u00c7evirme<\/p>\n
Merhaba! Ben Fatih Soysal ve bu yaz\u0131mda PyTorch’un g\u00fc\u00e7l\u00fc g\u00f6r\u00fcnt\u00fc i\u015fleme yeteneklerinden biri olan K\u0131saca a\u00e7\u0131klamak gerekirse, \u015eimdi, PyTorch kullanarak Bu basit \u00f6rnekte, Sonu\u00e7 olarak, #Etiketler <\/body>RandomInvert<\/code> fonksiyonunu detayl\u0131 olarak inceleyece\u011fiz. Bu fonksiyon, \u00f6zellikle veri art\u0131r\u0131m\u0131 s\u00fcre\u00e7lerinde olduk\u00e7a faydal\u0131d\u0131r ve modelinizin daha sa\u011flam ve genellenebilir olmas\u0131na katk\u0131da bulunur. \u00d6ncelikle, RandomInvert<\/code>‘in ne yapt\u0131\u011f\u0131n\u0131 anlamakla ba\u015flayal\u0131m.<\/p>\nRandomInvert<\/code>, bir g\u00f6r\u00fcnt\u00fcn\u00fcn renk kanallar\u0131n\u0131 rastgele bir olas\u0131l\u0131kla ters \u00e7evirir. Yani, her pikselin renk de\u011ferini 255’ten \u00e7\u0131kararak, g\u00f6r\u00fcnt\u00fcn\u00fcn renklerini negatifine d\u00f6n\u00fc\u015ft\u00fcr\u00fcr. Bu i\u015flem, \u00f6zellikle d\u00fc\u015f\u00fck \u0131\u015f\u0131k ko\u015fullar\u0131nda \u00e7ekilmi\u015f g\u00f6r\u00fcnt\u00fclerde veya kontrast\u0131 d\u00fc\u015f\u00fck olan g\u00f6r\u00fcnt\u00fclerde faydal\u0131 olabilir. Bununla birlikte, bu d\u00f6n\u00fc\u015f\u00fcm\u00fcn her zaman istenen bir etki yaratmayabilece\u011fini de belirtmekte fayda var. Bu y\u00fczden, rastgele bir olas\u0131l\u0131k ile uygulanmas\u0131 \u00f6nemlidir.<\/p>\nRandomInvert Nas\u0131l \u00c7al\u0131\u015f\u0131r?<\/h2>\n
RandomInvert<\/code>, belirli bir olas\u0131l\u0131k de\u011feriyle \u00e7al\u0131\u015f\u0131r. Bu de\u011fer, 0 ile 1 aras\u0131nda olmal\u0131d\u0131r. E\u011fer bu olas\u0131l\u0131k de\u011ferinden daha b\u00fcy\u00fck bir rastgele say\u0131 \u00fcretilirse, g\u00f6r\u00fcnt\u00fcn\u00fcn renk kanallar\u0131 ters \u00e7evrilir. Aktif hale geldi\u011finde, her pikselin renk de\u011ferleri 255’ten \u00e7\u0131kar\u0131l\u0131r. Bu sayede, ayd\u0131nl\u0131k b\u00f6lgeler koyu, koyu b\u00f6lgeler ise ayd\u0131nl\u0131k hale gelir. Bu i\u015flem, g\u00f6r\u00fcnt\u00fcn\u00fcn genel g\u00f6r\u00fcn\u00fcm\u00fcn\u00fc de\u011fi\u015ftirir ve modelin farkl\u0131 varyasyonlara kar\u015f\u0131 daha dayan\u0131kl\u0131 olmas\u0131na yard\u0131mc\u0131 olur. \u00d6rne\u011fin, e\u011fitim verilerinizde karanl\u0131k g\u00f6r\u00fcnt\u00fcler azsa, RandomInvert<\/code> ile bu eksikli\u011fi telafi etmeye \u00e7al\u0131\u015fabilirsiniz.<\/p>\nPyTorch ile RandomInvert Uygulama \u00d6rne\u011fi<\/h2>\n
RandomInvert<\/code> fonksiyonunu nas\u0131l kullanabilece\u011finizi basit bir \u00f6rnek ile g\u00f6sterelim. A\u015fa\u011f\u0131daki kod par\u00e7as\u0131nda, \u00f6ncelikle gerekli k\u00fct\u00fcphaneleri import ediyoruz. Daha sonra, bir \u00f6rnek g\u00f6r\u00fcnt\u00fc olu\u015fturup, RandomInvert<\/code>‘i uyguluyoruz ve sonucu g\u00f6r\u00fcnt\u00fcl\u00fcyoruz. Bu \u00f6rnekte, olas\u0131l\u0131k de\u011ferini 0.5 olarak ayarlad\u0131k, bu da g\u00f6r\u00fcnt\u00fcn\u00fcn %50 olas\u0131l\u0131kla ters \u00e7evrilece\u011fi anlam\u0131na gelir. <\/p>\n\nimport torch\nfrom torchvision import transforms\n\n# \u00d6rnek g\u00f6r\u00fcnt\u00fc olu\u015fturma (Rastgele bir tensor)\nimage = torch.rand(3, 256, 256)\n\n# RandomInvert transform'\u00fcn\u00fc olu\u015fturma\ninvert_transform = transforms.RandomInvert(p=0.5)\n\n# Transform'\u00fc uygulama\ninverted_image = invert_transform(image)\n\n# Sonucu g\u00f6r\u00fcnt\u00fcleme (Bu k\u0131s\u0131m g\u00f6rselle\u015ftirme i\u00e7in ek bir k\u00fct\u00fcphane gerektirir)\n# ...\n<\/code><\/pre>\ntransforms.RandomInvert(p=0.5)<\/code> ile bir RandomInvert<\/code> transform nesnesi olu\u015fturuyoruz. p<\/code> parametresi, ters \u00e7evirme i\u015fleminin uygulanma olas\u0131l\u0131\u011f\u0131n\u0131 belirler. Ard\u0131ndan, invert_transform(image)<\/code> sat\u0131r\u0131 ile bu transform’\u00fc \u00f6rnek g\u00f6r\u00fcnt\u00fcm\u00fcze uyguluyoruz. Sonu\u00e7 olarak, inverted_image<\/code> de\u011fi\u015fkeninde, isterseniz ters \u00e7evrilmi\u015f, isterseniz de orijinal g\u00f6r\u00fcnt\u00fc bulunur.<\/p>\nRandomInvert’in Veri Art\u0131r\u0131m\u0131’ndaki \u00d6nemi<\/h2>\n
RandomInvert<\/code>, veri art\u0131r\u0131m\u0131nda \u00f6nemli bir rol oynar. Veri art\u0131r\u0131m\u0131, mevcut e\u011fitim verilerinden yeni veriler \u00fcreterek modelin performans\u0131n\u0131 art\u0131rmaya y\u00f6nelik bir tekniktir. RandomInvert<\/code>, g\u00f6r\u00fcnt\u00fclerin renk \u00f6zelliklerini de\u011fi\u015ftirerek, modelin farkl\u0131 renk ko\u015fullar\u0131na kar\u015f\u0131 daha sa\u011flam olmas\u0131n\u0131 sa\u011flar. \u00d6zellikle s\u0131n\u0131rl\u0131 veri setleriyle \u00e7al\u0131\u015f\u0131yorsan\u0131z, RandomInvert<\/code> gibi veri art\u0131r\u0131m\u0131 tekniklerini kullanmak, modelin genellenebilirli\u011fini \u00f6nemli \u00f6l\u00e7\u00fcde iyile\u015ftirebilir. Bu sayede, modeliniz daha az veriyle daha iyi sonu\u00e7lar \u00fcretebilir.<\/p>\nRandomInvert<\/code>, PyTorch’ta g\u00fc\u00e7l\u00fc bir g\u00f6r\u00fcnt\u00fc i\u015fleme fonksiyonudur.
