Digital Image Processing Basics Quiz

Digital Image Processing refers to the manipulation and analysis of analog images using computer algorithms.

Digital image processing encompasses only simple tasks like image resizing and color correction.

In digital image processing, images are represented as continuous arrays of pixels.

The main goal of digital image processing is to worsen the visual appearance and interpretability of images.

Digital image processing techniques encompass a narrow range of operations such as image filtering and compression.

What is the main goal of image segmentation?

Name two approaches to image segmentation.

How does region-based segmentation divide an image?

What concept is watershed segmentation based on?

In what applications does segmentation play a vital role?

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.
