  • Image processing method and system
    Patent number: 11153468
    Abstract: A method of processing image data that is represented in a frequency domain includes the step of applying a noise signal to the image data to yield noise-applied image data. In at least one embodiment, the image data includes one or more sets of coefficients arising from application of a discrete cosine transform, each set of coefficients comprising a DC coefficient and one or more AC coefficients. The noise signal is applied to the image data by modifying one or more of the coefficients in one or more of the sets. The modifying includes replacing one or more of the AC coefficients with random or pseudo random numbers having a distribution. Noise present in the image data may be equalized, prior to the step of applying the noise signal.
