New spectral image compression method based on an optimal phase coding and the RMS duration principle

Abstract : By only using phase information, this manuscript describes a new spectral lossy compression method which can: Reduce required memories; adaptively retrieve original images by only using spectral phase information; and be easily employed in major encryption techniques. To increase the compression ratio of the proposed method, an optimal phase coding based on "a fading grid" is performed. In fact, a variable number of quantization bits has been used to quantize phase information depending on the importance of the spectral phases. The phase information could be classified according to the concept of "RMS Duration". Many simulations have been carried out. Our experimental results corroborate the performance of the new proposed method.
