Colour Image Encryption - A Wavelet Transformation Associated with Artificial Neural Network Approach
Prateep Upadhyay, S.K. Upadhyay · International Journal of Computer Applications · 2015
Image encoding decoding concept is studied by using the techniques of wavelet transformation, artificial neural network(ANN)and threshold value.The aforesaid techniques are useful in encoding and decoding.This process gives more ensured, a three leveled security to the images in three different terms.First is wavelet transformation.Second is encoding decoding keys along with weights of ANN and third is the threshold value for the decoding process.The decoding process does not start until the correct threshold value is entered.
