INTRODUCTION

ANNOTATION

Annotation is an easy to use application that allows you to code events in terms of their type, onset, and duration. Annotation can not only be used to generate organized audio or video clips but also to extract complex event structures and then analyze them using your favorite statistics software. In addition, Annotation’s interface helps you spot patterns by graphically visualizing your data. Annotation is very flexible: it was built for labs at major research institutions but is already also being used by students, focus groups, human and animal behavior labs, a variety of training environments ranging from nursing to sports coaching, as well as several smaller niches.

The annotation can be of different types according to the type of files in which the changes are being made, it can be of:

Web Annotation

A Web annotation is an online annotation associated with a web resource, typically a web page. With a Web annotation system, a user can add, modify or remove information from a Web resource without modifying the resource itself. The annotations can be thought of as a layer on top of the existing resource, and this annotation layer is usually visible to other users who share the same annotation system, making it a type of social software tool. (Wikipedia, the free encyclopedia

Document Annotation

A document annotation is an annotation associated with a document or a file that is not personal means that everyone can read it, make additions or modify it. The changes that have been made in the document then are visible to every user who will retrieve it afterward.

Image annotation

Image annotations include the changes being made in the images by editing them in different softwares that are nowadays available in the market. Image annotation includes improvement in the quality of the image; add some funny textures to it or combining two images together.

Video annotation
The main concern of us in this project is to work on the video annotations. The video annotation feature is a newly developed technique that helps us to add details in our video by making changes in the video clip. We can add notes to a clip, an image, some text, headings or combine two separate videos together to make them appear as they are the part of a single video, which will be visible to us during the playing video.

Video annotation tools

To annotate a video one must have a video annotation tool. The Video Annotation Tool lets you add notes to time segments on a video timeline. You can view the video clip, mark a time segment, play back the segment, or attach your written notes to the segment.
Video annotation tool is a special type of software that allows user to graphically interact with software and make changes in the videos.

Youtube

Youtube is an online video viewing website that allows users from all over the world to view and share different types of videos lying under different categories. It includes videos lying under the categories like Science and technology, Learning, Music etc. In fact all the types of videos can be viewed as well as downloaded from the Youtube website. Unregistered users can only view and download the videos available on the website while the registered users can also upload their own created video on the website that would be displayed to all the users who will access the site.

Annotation Feature

There are three currently useful types of annotations that are available on the youtube annotation feature:

  • Notes

Notes

Notes feature of annotation allows us to add text in a playing video. The added text will appear on the video at that particular time where the user would like the text to appear. This adds details to the video clip. As an example the text has been added to the clip that is visible at the bottom of the playing video.

Speech Bubble

Speech Bubble feature of the youtube let us allow to add a speech title in the playing video we can add the comments to the playing video. The comment can be of any type it can be to explain the video or either to create humor in the video. The addition of a speech bubble to the video helps in adding detail to the video it also helps in creating interest in the video. The example of speech bubble added to a video is shown below.

Spot-light

Spot-light annotation is a type of annotation that is being added in the video to highlight a particular point. It is to mention the importance of that point or that image clearly in the video so that the viewer will focus only that point of the screen.

Pause annotation

Pause annotation is a type of annotation feature that helps to pause the video for a certain period of time and that part of the video clip is then visible to the viewer in the pause state i.e. the video will not move and will be stopped at that particular moment.
