Applications of Feature Extraction for Image Processing
- Object Recognition: Edges are features that are used to differentiate images from the background, textures and shapes of images are features used to differentiate between images within an image.
- Facial Recognition: Other factors such as facial symmetry and convexity, face shape and size, distance between eyes and distance across base of nose, size of forehead and distance across forehead, cheek and cheekbone size and paral distance, vertical height or size of face below line and between the eyes, jaw size and shape, nose size and shape, and size of the lips also have an effect on face categorisation.
- Medical Imaging: It is therefore evident that in medical diagnostics MRI or CT image it may possible to capture such characteristic in MRI or CT to analyze anomalies of tumors that may be caused by a disease at a high success probability.
- Remote Sensing: Features like Vegetation Index, water bodies and urban areas provided from the satellites are very valuable for doing the environmental mapping.
- Content-Based Image Retrieval (CBIR): Retrieving images from a database based on the content of the images rather than metadata.
Feature Extraction in Image Processing: Techniques and Applications
Feature extraction is a critical step in image processing and computer vision, involving the identification and representation of distinctive structures within an image. This process transforms raw image data into numerical features that can be processed while preserving the essential information. These features are vital for various downstream tasks such as object detection, classification, and image matching.
This article delves into the methods and techniques used for feature extraction in image processing, highlighting their importance and applications.
