Encode a picture using the HOG algorithm to create a simplified version of the image. Facebook automatically tags people in your photos that you have tagged before. Then we could measure our unknown face the same way and find the known face with the closest measurements.
Hans Burkhardt who accompanied me during my thesis, gave me helpful advice and who nbsp; Chapter Two — Idsia The above thesis, submitted in partial fulfillment of the requirements for the degree of and the Self-Organizing Map SOM Neural Network for recognition purpose, 2.
Lucky for us, the fine folks at OpenFace already did this and they published several trained networks which we can directly use. When the camera can automatically pick out faces, it can make sure that all the faces are in focus before it takes the picture.
The basic idea is we will come up with 68 specific points called landmarks that exist on every Face recognition using neural networks thesis — the top of the chin, the outside edge of each eye, the inner edge of each eyebrow, etc.
Example of a CNN. The exact approach for faces we are using was invented in by researchers at Google but many similar approaches exist. We need to build a pipeline where we solve each step of face recognition separately and pass the result of the current step to the next step.
For example, we might measure the size of each ear, the spacing between the eyes, the length of the nose, etc. First, look at a picture and find all the faces in it Second, focus on each face and be able to understand that even if a face is turned in a weird direction or in bad lighting, it is still the same person.
Pass the centered face image through a neural network that knows how to measure features of the face. Bachelor of Science, Advisor: The other is Chad Smith.
But instead of training the network to recognize pictures objects like we did last time, we are going to train it to generate measurements for each face. In fact, humans are too good at recognizing faces and end up seeing faces in everyday objects: Seems like a pretty good idea, right?
The system consists of three stages. Deep learning does a better job than humans at figuring out which parts of a face are important to measure. After repeating this step millions of times for millions of images of thousands of different people, the neural network learns to reliably generate measurements for each person.
As a human, your brain is wired to do all of this automatically and instantly. Once we find those landmarks, use them to warp the image so that the eyes and mouth are centered. When we find a previously tagged face that looks very similar to our unknown face, it must be the same person.
You can do that by using any basic machine learning classification algorithm. Figure out the pose of the face by finding the main landmarks in the face.
So what parts of the face are these numbers measuring exactly?
Now as soon as you upload a photo, Facebook tags everyone for you like magic: The simplest approach to face recognition is to directly compare the unknown face we found in Step 2 with all the pictures we have of people that have already been tagged. That makes the problem a lot easier to solve!
This technology is called face recognition.
You run it like this. If you liked this article, please consider signing up for my Machine Learning is Fun! What we need is a way to extract a few basic measurements from each face. The original image is turned into a HOG representation that captures the major features of the image regardless of image brightnesss.
We end up missing the forest for the trees. Any ten different pictures of the same person should give roughly the same measurements. That would take way too long.Machine Learning is Fun!
