Abstract

Fractional transforms not only enhance the overall signal processing applications but also improved the efficacy of systems. In this paper, we focus to present several image processing techniques using fractional transforms under one umbrella. The primary motive of this paper is to study the image related literature survey, formats, noises, performance parameters, websites and open issues to encourage further research in this area. The paper first describes fractional transforms and in the second part, we provide comprehensive and exhaustive details on the use of these transforms in image processing. Specific topics include image compression, encryption, enhancement, rotation, watermarking etc. Some technical image processing challenges like thresholding, CPU time etc., are also discussed with a future scope.
