ABSTRACT

The problem of digital storage is an eternal dilemma that will be there in the future as well and haunted the past researchers relentlessly. There always has been a trade-off within the choice of quality vs. quantity in all fields of life, and Digital Data storage is not an exception for sure. Our root focus will be the storage of Videos at extensive facilities that need to store colossal amounts of recording for their specific purposes. One crucial example that we would like to unravel would be CCTV footage at facilities/public places for security purposes. The footage always seems to be of bleak quality, and the details are elusive even if the incident is quite recent. This trade-off of quality sounds comprehensible since the main focus remains on having the maximum length of footage as possible. We thereby propose a time-dependent compression technique that satisfies the need of the hour. The concept suggests different levels of compression based on the age of the recorded video. The study finds the dependence of block size with the time taken for compression and, in turn, finds its performance with the help of metrics like Object Identification, Motion Tracking, Activity Recognition, and Mean Squared Error. The user is free to choose from the compression stages mentioned based on the specific application and other essential parameters like Storage capacity.
