How face recognition is different from face detection A history of face recognition algorithms State-of-the-art algorithms used for face recognition today Next week we will start implementing these face recognition algorithms. To learn about face recognition, just keep reading. Looking for the source...

Usingrects = gs.process(rects)sets rects toNoneand causes the program to terminate with an exception. OpenCV version is 3.2.0. Using a numpy array instead of a python list crashes my program with the following message: OpenCVError:Assertionfailed (channels()==CV_MAT_CN(dtype))in...
Object recognition is an AI vision technique to identify the presence of objects in digital images or videos. Learn more about its types, and its benefits.
I've converted some PIL library function to OpenCV function, but I can't find a substitute of the following function using OpenCV functions. Here is the PIL library function: img = ImageEnhance.Contrast(image).enhance(param) python opencv image-processing python-imaging-lib...

According to Sklaski, One of the most basic tasks in computer vision is face detection. In order to approach this, he chose to use the Haar Cascade classifier, a well-known technique made available by OpenCV. Even while Haar Cascade is an effective face recognition method, it has certain ...
We can say, ‘Hey Siri, show me the closest fast-food restaurant’ or ‘Who is the 21st President of the United States?’, and my AI assistant will respond with the relevant information by either going through your phone or searching it on the web. This is a simple example of ...
For example, I have a project that needs Python 3.5 using OpenCV 3.3 with older Keras-Theano backend but in the other project I have to use Keras with the latest version and a Tensorflow as it backend with Python 3.6.6 support We don’t want the Keras library to conflict at each other...
