What is Object Detection ?

Object Detection is a computer technology related to computer vision and image processing that deals with detecting instances of semantics objects of a certain . (Wikipedia Definition)

 This task involves both identification of the presence of the objects and identification of the rectangular boundary surrounding each object (i.e. Object Localisation).

 An object detection system which can detect the class “Human” can work as a Human Detection System .

We can detect human using following algorithm 

1. Haar cascade  ( Research paper Haar Cascade )
2. HOG based approaches 


1. Haar Cascade Approach : 

This is proposed by Paul Viola and Michael Jones in their paper “Rapid Object Detection using a Boosted Cascade of Simple Features” published in 2001. This approach is widely used for Face Detection .

2. Histograms of Oriented Gradients for Human Detection

This is proposed by N. Dalal and B. Triggs in their paper “Histograms of oriented gradients for human detection” published in 2005.
