LITERATURE SURVEY
1. Video Summarization Techniques Landscape
Video contents have dominated our fast-paced digital lives, but because of staggering amounts of content available online, it can get hard to process. Hence, with the increased interest in summarizing techniques of video content, it has allowed viewers easy digestion of large amounts of information quickly.[5]
In this paper, we demonstrate the subtlety of Distinguishing various video summarization techniques, dig into the technological foundation, and survey the current systems while navigating through this space to discover potential new inventions.
2. The Video Summarization Techniques
Video summarization can be broadly categorized into two techniques: visual-based summarization and text-based summarization. However with each comes its strength and weakness within the method.
3. Visual-Based Summarization
Visual-based summarization is based on visual features existing in a video. This summarization technique focuses on key frames or shots, which represent the summation content as a whole.
* Keyframe Extraction/Shot Boundary Detection According to Money and Agius (2008), generic methods involve keyframe extraction and shot boundary detection. While these techniques are frequently employed, it makes them messy and computationally intensive, especially when it comes to algorithms that are specific to a particular domain, which makes generalization across different platforms difficult.
*Video Skimming*: This generates a summary of the video, enabling a viewer to grasp the overall idea in a short period without having to view the video at its full length. There are various visual summarization tools; however, they require substantial computational costs that can be off-putting to non-developer users.
4. Text-Based Summarization
Text-based summarization relies upon the textual information available with the video, such as transcriptions, captions, or description. Over the years, this technique has become pretty popular because of the advancements developed in the field of Natural Language Processing (NLP)
NLP Techniques: Mokhtari et al. (2018)[4][9][20] prefer to use NLP technology to convert raw transcriptions to a coherent summary. They can therefore distill the essence of the video efficiently through various algorithms.
*Alignment with our Project Goals: The ultimate goal of this blog post is to back up a project that aims at creating shorthand video summaries, based exclusively on descriptions found on the internet.
5. Natural Language Processing's Role
Natural Language Processing is an extremely advanced field, and transformer-based models - BERT and GPT for example - dramatically revolutionized the task of summarization.
