Recorded image sequences, or video for short, may have severe degradations in many conditions even with the advancements in camera and digital recording technologies. Low recording conditions, such as those seen in astronomy, forensic sciences, and medical imaging, may be to blame for the poor quality of captured image sequences. In these application fields, video enhancement and restoration have always been crucial to raise the performance of future activities like analysis and interpretation as well as the visual quality.
What is Forensic Video Enhancement?
Forensic video enhancement is a scientific digital investigative procedure that aims to improve the sharpness and clarity of video footage that will be used as evidence in court. Of course, the problem is to maintain its integrity while obtaining the highest level of clarity and visibility.
Notable Issues Related To Video Forensics
Forensic video analysis is not always as simple as it seems. During the digital forensics process, a forensic video analyst may run into a number of obstacles, including but not limited to:
- Unfavorable weather
- Bad lighting
- Distance
- Unreliable recording medium
- Damaged or poor quality recording equipment
- Awkward angle for capturing
- Inappropriate recording speed
These unfavorable circumstances can make things difficult in court. In other words, before the judicial system will accept these recordings and allow them as evidence, competent forensic video enhancement is required.
Importance Of Video Enhancement
Preserving motion pictures and video cassettes shot during the past century is a significant application of video enhancement and restoration. Due to the aging effects of the actual film reels and magnetic tapes that carry the information, these unique recordings of historical, artistic, and cultural advances are degrading quickly. Broadcasters are likewise interested in the preservation of these fragile archives as a cheap alternative to fill the numerous television channels that have become accessible with digital broadcasting.
However, it is only practical to reuse vintage film and video if the visual quality is up to date. The stored film and video are first transferred to digital media from the original film reels or magnetic tape.
In addition, the digitized image sequences are then cleaned up from all kinds of flaws, improving their visual quality and boosting their marketability.
Restoration returns the original spatial and temporal correlation structure of digital image sequences by purging irrelevant information, such as noise and blotches. Restoration may therefore enhance the effectiveness of the subsequent MPEG compression of visual sequences.
