You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
Image ProcessingImage processing is the cornerstone in which all of Computer Vision is built. Follow my image processing guides to learn the fundamentals of Computer Vision using the OpenCV library.
In this tutorial, you will learn how to use OpenCV and GrabCut to perform foreground segmentation and extraction. Prior to deep learning and instance/semantic segmentation networks such as Mask R-CNN, U-Net, etc., GrabCut was the method to accurately segment the…

One of my favorite photography techniques is long exposure, the process of creating a photo that shows the effect of passing time, something that traditional photography does not capture. When applying this technique, water becomes silky smooth, stars in a…

After our previous post on computing image colorfulness was published, Stephan, a PyImageSearch reader, left a comment on the tutorial asking if there was a method to compute the colorfulness of specific regions of an image (rather than the entire…
