Filtering

Filtering is a fundamental operation in image and video processing. It involves selectively modifying the values of pixels in an image or video frame based on certain criteria, such as their color, brightness, or spatial properties. Filtering can be used to enhance the visual appearance of images and videos, remove noise, extract specific features, and perform various other image analysis tasks.

Why Learn About Filtering?

There are many reasons why one might want to learn about filtering. Some of the most common reasons include:

• Image and video enhancement: Filtering can be used to improve the visual appearance of images and videos by adjusting their contrast, brightness, color balance, and other properties.
• Noise reduction: Filtering can be used to remove noise from images and videos, which can be caused by factors such as camera sensor noise, compression artifacts, or environmental factors.
• Feature extraction: Filtering can be used to extract specific features from images and videos, such as edges, corners, and objects. This information can be used for various purposes, such as object recognition, tracking, and segmentation.
• Image analysis: Filtering can be used to perform various image analysis tasks, such as measuring the size and shape of objects, detecting defects, and identifying patterns.
