Abstract
In this paper, a new definition for images named as the sensitivity parameter (SP) is introduced. SP is based on the decreasing rate of singular values in an image. It could be used in compressing images in a lower bit rate or in distinguishing robust image parts against watermarking. SP could also be used when we would want to make changes in pixel values but keep the quality of the image as it is.
