Introduction

Image segmentation and feature extraction are crucial steps in many image analysis and computer vision applications. Image segmentation involves partitioning an image into multiple regions or segments, making it easier to analyze. Feature extraction then involves identifying and extracting relevant information from these segmented regions. These techniques are vital for tasks such as object recognition, medical image analysis, remote sensing, and automated inspection. This course provides a comprehensive overview of both image segmentation and feature extraction, covering both classical and modern approaches. Participants will gain hands-on experience with various algorithms and tools, enabling them to apply these techniques effectively in their own projects. The course aims to bridge the gap between theory and practice, ensuring that participants can confidently tackle real-world image analysis challenges.
