An Analytical Survey on Image Compression

There has been a significant increase in the number of smartphones and other devices that have been highly useful as a means of communication and entertainment. Therefore, there is a need to secure such devices as the majority of the smartphones that are being sold have been equipped with inbuilt biometric authentication system. Facial features are very diverse and have some kind of similarity with features in other people's faces, especially relatives and siblings. Therefore, there is a need to offload the facial authentication system and the recognition images to the cloud platform for computation. To this end, this research article has analyzed the past works based on the facial image compression paradigm for their improvements and limitations to assist in the implementation of a fast and effective facial image compression technique that will be discussed in detail in the upcoming publications.
