Blobscounterla şekillerin kenar piksellerini belirleyip elips bir cismin şeklini bulmak istiyorum ama bir türlü kenarları çizdiremedim.Kodu çalıştırdığımda objeleri buluyor ama objelerin her pikseli kırmızı oluyor.Bu konuda bilgisi olan biri cevap verebilirse sevinirim.Ayırt etmek istediğim şekil şu:
