The main objective of image compression is to compress the size of an image file by removing the repetitive data sequences and therefore enable effective storage and management of data. Two different compression techniques are used for image compression: lossy and lossless compression. Run-length encoding, area image compression, predictive coding and entropy coding are a few examples of the methods of lossless compression. Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
