Your Ultimate Guide to Image Segmentation Models
Image segmentation is a fundamental task in computer vision that involves partitioning an image into meaningful regions or segments. These models are widely used in various industries, including healthcare, automotive, agriculture, and entertainment. This article explores the key workloads, strengths, drawbacks, and frequently asked questions about image segmentation models, providing a detailed and comprehensive understanding of the topic.
What are Image Segmentation Models?
Image segmentation models are algorithms designed to classify each pixel in an image into specific categories or regions. Unlike traditional image classification, which assigns a single label to an entire image, segmentation models focus on identifying and delineating objects or areas within the image. This pixel-level classification enables precise analysis and manipulation of visual data.
There are two primary types of image segmentation:
- Semantic Segmentation: Assigns a class label to each pixel in the image, grouping pixels with similar characteristics into regions. For example, in a street scene, semantic segmentation might label all pixels belonging to cars, pedestrians, and buildings.
- Instance Segmentation: Extends semantic segmentation by distinguishing between individual objects within the same class. For instance, it can identify multiple cars in a scene and assign unique labels to each.
