free code for reversible image data hiding with contrast enhancement - pradeep - 08-17-2017 This system is proposed for digital images, mainly focussed on grey scale images. Usual algorithms just keep the PSNR values high to enhance the contrast of an image, where this system enhances the image quality as well as its security and decreases the bandwidth consumed. For embedding data in the image highest two peaks in the histogram are selected and then repeated the same process for performing histogram equalization. The data is embedded in the image, compressed and encrypted using chaotic encryption such that the data and image are completely recoverable. The system with the proposed algorithm was performed on two sets of images to prove its efficiency. It is found that, by embedding considerable amount of data into the image, the contrast of the image is being enhanced. It is proved that, this system works better than the three inbuilt MATLAB functions for contrast enhancement which as an add-on provides compression and encryption for better security. free code for reversible image data hiding with contrast enhancement - binithekkethil - 08-17-2017 hi.. my name is richard. i would like to get details on free code for reversible image data hiding with contrast enhancement. Can you give me free code? |
