  • The dithering technique based on the Laplacian model for AC coefficients is proposed in Ref. 5 to perform DCT histogram smoothing.
  • dithering operation
  • adaptive dithering
  • dithering model

One of the classic approaches used is what's called Floyd Steinberg dithering.

Examples

  • OK, so the two pictures are both quantized at the level of seven bits, but the one on the right had dither added to it first.

  • Therefore, the resultant image processed through the dithering operation can be recognized as an anti-forensically processed image.

  • AFV represents the perceptual anti-forensic dithering method 9.

    Academic text (2017)

  • AFSqSb denotes the anti-forensic method based on dithering and deblocking operation 6.

    Academic text (2017)

  • The proposed dithering operation 5 was successfully able to fool the detector proposed in Ref. 3, which investigates the DCT domain artifacts.

    Academic text (2017)

  • Furthermore, in Ref. 19, a JPEG anti-forensic approach was presented, which is based on the dithering, denoising, and deblocking operation.

    Academic text (2017)

  • A JPEG anti-forensic technique was presented in Ref. 20, which includes an adaptive local dithering model, TV (total variation) based deblocking, and decalibration operation.

    Academic text (2017)

  • The anti-forensic technique AFV, based on the perceptual dithering scheme, achieves a high SSIM value, but its forensic undetectability is comparable to the AFSq technique.

    Academic text (2017)

  • In digital art, dithering helps create smoother gradients by mixing colors in small patterns.

  • The artist used dithering techniques to enhance the image, making it appear more vibrant and detailed.

dithering singular
ditherings plural

Morphology

dithering = dither (semi-transparent) = dither + ing

Regular gerund formation from the verb 'dither', but the technical imaging meaning is specialized and not fully predictable from the general verb sense.

Etymology

Dithering comes from the older verb dither, which once meant 'to tremble' or be nervous. In digital imaging, dithering is like giving colors a tiny 'shake'—placing small dots or noise so hard steps between colors are hidden and the picture looks smoother.
