Patent ID: 8224104

Claim:
A system for predicting a file size of an image subject to transformation by scaling and a change of a quality factor, the quality factor being inversely proportional to a quantization parameter of the image, the system comprising: a processor, and a non-transitory computer readable storage medium having computer readable instructions stored thereon for execution by the processor, causing the processor: to receive (a) a file size of the image before the transformation of the image, (b) information about a quality factor of the image before the transformation, (c) information about a quality factor of the image to be applied to the image during the transformation, and (d) a resolution scaling factor to be applied to the image during the transformation; and to form: a calculator for determining a relative file size prediction of the image after the transformation based on the received information about the quality factor of the image before the transformation, the quality factor of the image to be applied during the transformation, and the resolution scaling factor; and a calculator for determining a file size prediction of the image after the transformation as a function of the file size of the image before transformation and the relative file size prediction.
