Segmentation and feature extraction are two important tasks in digital image processing that help in understanding and analyzing the content of an image. 1. Segmentation: Image segmentation refers to the process of partitioning an image into multiple regions or segments based on certain criteria, such as color, intensity, texture, or object boundaries. The goal of segmentation is to separate different objects or regions of interest within an image to enable further analysis or understanding. Segmentation techniques can be categorized into several approaches, including: Thresholding: Simple technique where pixels are classified as foreground or background based on a predefined threshold value. Region-based segmentation: Divides an image into regions based on similarities in color, texture, or other image properties. SEGMENTATION AND FEATURE EXTRACTION Edge-based segmentation: Focuses on detecting boundaries or edges between different objects in an image. Clustering-based segmentation: Utilizes clustering algorithms to group similar pixels or regions together. Watershed segmentation: Based on the concept of flooding regions starting from local minima or markers. Segmentation plays a vital role in various applications, such as medical image analysis, object detection, scene understanding, and image-based measurements. SEGMENTATION AND FEATURE EXTRACTION 2.
Feature extraction is the process of obtaining meaningful information from the segmented regions of an image, which can be used for further analysis or classification.
