OpenCV Saliency Detection - PyImageSearch

Today's tutorial is on saliency detection, the process of applying image processing and computer vision algorithms to automatically locate the most "salient" regions of an image. In essence, saliency is what "stands out" in a photo or scene, enabling your eye-brain connection to quickly (and essentially unconsciously) focus on the most important regions. For example -- consider the figure at the top of this blog post where you see a soccer field with players on it. When looking at the photo, your eyes automatically focus on the players themselves as they are the most important areas of the photo. This automatic process of locating the important parts of an image or scene is called saliency detection.
