What is Digital Image Processing?

Digital image processing is a subfield of digital signal processing that deals with the processing and manipulation of digital images. It involves the use of algorithms and techniques to perform various operations on images, such as image enhancement, image restoration, image segmentation, and image compression.

Applications of Digital Image Processing

Digital image processing has numerous applications across various fields, including:

1. Medical Imaging: Image processing techniques are used to enhance and analyze medical images, such as X-rays, CT scans, and MRI scans.
2. Computer Vision: Digital image processing is used in computer vision applications, such as object recognition, tracking, and scene understanding.
3. Remote Sensing: Image processing techniques are used to analyze and interpret satellite and aerial images.
4. Security and Surveillance: Digital image processing is used in security and surveillance systems, such as facial recognition and object detection.
