What is the difference between image segmentation and segmentation algorithm?


Asked by Elijah Spencer on Dec 11, 2021 FAQ



In computer vision the term “image segmentation” or simply “segmentation” refers to dividing the image into groups of pixels based on some criteria. A segmentation algorithm takes an image as input and outputs a collection of regions (or segments) which can be represented as
Moreover,
Segmentation is the process of extracting smaller segments out of one image with the intent of identifying different parts/objects within an image. So for example segmentation of an image can give you back ground and fore ground separately. This is usually done using traditional image processing algorithms like edge detection, PCA etc.
In addition, For semantic segmentation, the algorithm is intended to segment only the objects it knows, and will be penalized by its loss function for labeling pixels that don't have any label. For example the MS-COCO dataset is a dataset for semantic segmentation where only some objects are segmented.
Indeed,
That, in a nutshell, is how image segmentation works. An image is a collection or set of different pixels. We group together the pixels that have similar attributes using image segmentation. Take a moment to go through the below visual (it’ll give you a practical idea of image segmentation):
Furthermore,
And there is a one difference between both of them. The classification process is easier than segmentation, in classification all objects in a single image is grouped or categorized into a single class. While in segmentation each object of a single class in an image is highlighted with different shades to make them recognizable to computer vision.
