Data Embedding an Image Using DCT Compression
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 6
Abstract
This paper concerns with the hybrid technique that combines image compression and encryption to have an embedded image along with data that's secure and can be manipulated with a secure key. The compression of image can be done by reducing the size of image which is performed with the help of transforms. DCT Type 2 is the base algorithm used for image compression. In this paper we have taken the input image and applied modified cosine and wavelet techniques for image compression. Both the transform methods are compared in properties like RMS error, image intensity and execution time is concerned and the potential translation application in compression problem for cipher mutation of compressed images is suggested.
