Object Tracking - Optical Flow

Kategori: Computer Vision, 25 Şubat 2020
Object Tracking - Optical Flow

Object Traking, obje takibine giriş yapıyoruz. İlk göreceğimiz algoritma Optical Flow algoritması. Optical Flow algoritması temel olarak iki varsayıma dayanıyor:

1- Hareket eden objenin piksel yoğunluğu aynı kalacak.
2- Haraket eden objenin etrafındaki pikseller ... Devamını Oku

Brute Force Feature Matching

Önceki yazılarımda feature extraction algoritmalarını anlattım. Bu yazımızda daha önce çıkardığımız feature descriptorleri eşleştirerek, obje tespiti yapacağız. Feature matching için kullanacağımız ilk yöntem Brute-Force Matcher algoritması olacak. cv2.BFMatcher() sınıfından obje oluşturup kullanabiliriz.

Eşleşmeleri oluşturduğumuzda ... Devamını Oku

Oriented FAST and Rotated BRIEF

Şimdilik son algoritmamız olan Oriented FAST and Rotated BRIEF, diğer adıyla ORB algoritmasını inceleyeceğiz. Adından da anlaşılacağı gibi arkaplanda FAST ve BRIEF algoritmalarının geliştirilmiş versiyonlarını çalıştırıyor. FAST algoritmasını henüz görmedik fakat FAST algoritmasında oriented özelliği ...

Binary Robust Independent Elementary Featutures

SIFT algoritmasında feature descriptorlar için 128 boyutlu bir vektör kullanıyorduk. SURF algoritması da 64 boyutlu vektör kullanıyordu. Bu vektörlerin boyutları 512 byte ve 256 byte. Düşük görünebilir fakat genellikle bir resim için binlerce vektör oluşmakta. ... Devamını Oku

SIFT - Scale Invariant Feature Transform

Feature extraction için kullanışlı algoritmalardan bahsedeceğim serinin ilk yazısını yazıyorum. İnceleyeceğimiz algoritma Scale Invariant Feature Transform yani SIFT algoritması. 2004 yılında David Lowe tarafından bulunmuştur. Algoritma lisanslıdır, patentlidir.

Canny Edge Detection

Canny Edge Detection algoritmasının detayına inelim. Algoritma Sobel algoritmasına oldukça benziyor. Hatta ilk aşaması hemen hemen aynı. Fakat Canny algoritması, Sobel algoritmasından farklı olarak kenarları inceltme ve linking yöntemlerini kullanıyor. Algoritma 3 önemli aşamadan oluşuyor. ... Devamını Oku
