What is the term used to describe the process of extracting meaningful information from video data?

  1. Video Summarization

  2. Video Segmentation

  3. Video Compression

  4. Video Restoration


Correct Option: A
Explanation:

Video summarization involves analyzing video content and generating a concise representation that captures the key moments, events, or information. It helps users quickly grasp the essence of a video without having to watch the entire footage.

Which technique is commonly used for video segmentation, dividing a video into meaningful segments or shots?

  1. Edge Detection

  2. Clustering

  3. Optical Flow

  4. Histogram of Oriented Gradients (HOG)


Correct Option: B
Explanation:

Clustering algorithms are often employed for video segmentation. They group together similar frames or shots based on visual features, such as color, texture, or motion patterns, to identify distinct segments within a video.

What is the primary objective of video compression techniques?

  1. Reducing the file size of a video without compromising quality

  2. Improving the visual quality of a video

  3. Enhancing the audio quality of a video

  4. Converting a video into a different format


Correct Option: A
Explanation:

Video compression aims to reduce the size of a video file while maintaining its visual quality. This is achieved by removing redundant information and applying various encoding techniques to minimize the file size without significantly affecting the viewer's experience.

Which video compression standard is widely used for streaming high-quality videos over the internet?

  1. H.264

  2. MPEG-4

  3. VP9
