How to detect face in image using PHP

-
In brief: Three libraries for face detection with PHP: PHP-script with OpenCV, PHP FaceDetection, and Python FaceDetect script. FaceDetector library with OpenCV uses Haar Cascades. PHP FaceDetection can find only one face on a photo. Smart face detection is used in social networks, image editors, video chats, smart captcha, time tracking programs, etc. Option №1 FaceDetector on PHP is quite a successfull solution which uses OpenCV. FaceDetector works stably with various skin tones, low quality pictures, lots of faces and people wearing glasses. Operation algorithm Face detection here is based on Viola-Jones method, Haar Cascades (rectangular primitives), and AdaBoost learning algorithm. The primitives are black and white rectangles of different sizes which are placed on the image. After superimposing their correlation with a picture is being read.  FaceDetector installation First, packages install is nee...

The future of Artificial Intelligence: 6 ways it will impact everyday life

Technology moves at breakneck speed, and we now have more power in our pockets than we had in our homes in the 1990s. Artificial intelligence (AI) has been a fascinating concept of science fiction for decades, but many researchers think we’re finally getting close to making AI a reality.  NPR notes that in the last few years, scientists have made breakthroughs in “machine learning,” using neural networks, which mimic the processes of real neurons. This is a type of “deep learning” that allows machines to process information for themselves on a very sophisticated level, allowing them to perform complex functions like facial recognition. Big data is speeding up the AI development process, and we may be seeing more integration of AI technology in our everyday lives relatively soon. While much of this technology is still fairly rudimentary at the moment, we can expect sophisticated AI to one day significantly impact our everyday lives. Here are 6 ways AI might affect us in the ...
