Deep Learning algorithms

A Brief History of Image Recognition and Object Detection

Our story begins in 2001; the year an efficient algorithm for face detection was invented by Paul Viola and Michael Jones. Their demo that showed faces being detected in real time on a webcam feed was the most stunning demonstration of computer vision and its potential at the time. Soon, it was implemented in OpenCV and face detection became synonymous with Viola and Jones algorithm.

Every few years a new idea comes along that forces people to pause and take note. In object detection, that idea came in 2005 with a paper by Navneet Dalal and Bill Triggs. Their feature descriptor, Histograms of Oriented Gradients (HOG), significantly outperformed existing algorithms in pedestrian detection.

Every decade or so a new idea comes along that is so effective and powerful that you abandon everything that came before it and wholeheartedly embrace it. Deep Learning is that idea of this decade. Deep Learning algorithms had been around for a long time, but they became mainstream in computer vision with its resounding success at the ImageNet Large Scale Visual Recognition Challenge (ILSVRC) of 2012. In that competition, an algorithm based on Deep Learning by Alex Krizhevsky, Ilya Sutskever, and Geoffrey Hinton shook the computer vision world with an astounding 85% accuracy — 11% better than the algorithm that won the second place! In ILSVRC 2012, this was the only Deep Learning based entry. In 2013, all winning entries were based on Deep Learning and in 2015 multiple Convolutional Neural Network (CNN) based algorithms surpassed the human recognition rate of 95%.

With such huge success in image recognition, Deep Learning based object detection was inevitable. Techniques like Faster R-CNN produce jaw-dropping results over multiple object classes. We will learn about these in later posts, but for now keep in mind that if you have not looked at Deep Learning based image recognition and object detection algorithms for your applications, you may be missing out on a huge opportunity to get better results.
