Smile Detection with Python, OpenCV, and Deep Learning

Smile Detection with Python, OpenCV, and Deep Learning

June 23 2022 Yacine Rouizi
OpenCV Computer Vision Face Detection Object Detection

In this tutorial, we will use deep learning to build a more robust smile detector than the one we built in the previous tutorial where we used a Haar cascade smile detector. We will use the SMILES dataset to train our convolutional neural network...

Overfitting and Underfitting in Deep Learning

Overfitting and Underfitting in Deep Learning

June 6 2022 Yacine Rouizi
Keras and TensorFlow Deep Learning

There are two major problems when training neural networks: overfitting and underfitting. Overfitting is a problem that can occur when the model is too sensitive to the training data. The model will then fail to generalize and perform well on new data...

Keras and TensorFlow Deep Learning

Training a deep neural network can take hours or even days to complete. It is not practical to train such a neural network every time you want to make predictions. In this case, you can save and then later reload your model.

How to Rotate Images with OpenCV and Python

How to Rotate Images with OpenCV and Python

April 1 2022 Yacine Rouizi
OpenCV Image Processing

In this tutorial, we will see how to rotate images with OpenCV using some built-in functions. The first one is cv2.getRotationMatrix2D which, as its name suggests, will give us the transformation matrix that we will use to rotate the image ...
