Types of Artifacts in Video Compression

The ubiquitous presence of smartphones around the world & the impact of social media has resulted in increased video content generation and distribution. With limited storage disk or limited bandwidth of transmission channel, there is a need for good compression without degrading video quality.

In this paper, we present various types of artifacts (affecting video quality adversely) along with their root causes.

This document sheds light on the following points:

• Introduction of Video compression
• Classification of Video Compression Artifacts
• Temporal Artifacts
•  Spatial Artifacts
• Methodologies to detect artifacts
• Conclusion of the topic
