Join Carlos Rivas for an in-depth discussion in this video Intro: Facial recognition, part of Code Clinic: Java.
- [Narrator] Hello and welcome to the 5th problem…of the Code Clinic series.…This is a challenge to find faces in a photograph.…50 years ago, this problem would have been…difficult or impossible.…The technology and algorithms for facial recognition…were just being created.…Computers were barely powerful enough…to run the algorithms,…and it could take hours to recognize one face.…Today, we have real time performance…and use it as a security device…on some mobile computers.…
In this challenge,…we're asking our authors to demonstrate…how to do this with their programming language.…We've challenged our authors…to create a function that does the following.…First, the function should accept a jpeg,…gif, or png file of varying dimensions.…Their function should then identify…the number of faces in that image.…There may not be any faces,…in which case the function should return zero.…If the author chooses to go for extra credit,…their function can create a copy of the image…with the faces visually identified,…either with a surrounding box or other method.…
