You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
OpenCV TutorialsLearn how to successfully use, operate, and apply the OpenCV library for Computer Vision and Deep Learning using these free OpenCV tutorials and guides.
In this tutorial, you will learn how to perform automatic age detection/prediction using OpenCV, Deep Learning, and Python. Age detection models need a vast range of facial data across all age groups. A curated dataset library would provide the…
