...Since the primary focus of the proposed work is to limit the reconstruction error within pre-specified values, we imposed limit to percentage root mean squared difference normalized (PRDN) values at 3% and 5%, and calculated the performance indices like Compression ratio (CR), mean square error (MSE), and maximum absolute error (MAE) [20]....
