Threshold segmentation techniques grouped in classes: x Local techniques are based on the local properties of the pixels and their neighbourhoods. ), self-driving cars (localizing pedestrians, other vehicles, brake lights, etc. ), satellite image interpretation (buildings, roads, forests, crops), and more.. 2.1.1 Traditional Thresholding (Otsu’s Method) In image processing, segmentation is often the first step to pre-process images to extract objects of interest for further analysis. Detection of Similarities- Thresholding  Thresholding is the simplest, powerful and most frequently/widely used technique for image segmentation  It is useful in discriminating foreground from the background. What’s the first thing you do when you’re attempting to cross the road? The simplest method of image segmentation is called the thresholding method. x Global techniques segment an image on the basis of information obtain globally (e.g. Our brain is able to analyze, in a matter of milliseconds, what kind of vehicle (car, bus, truck, auto, etc.) Clustering based segmentation techniques: Starting from a rough initial clustering of pixels, gradient ascent methods iteratively refine the … Basically, what we want is the output image in the slide … See our User Agreement and Privacy Policy.
