Dither directed LUT output value interpolation

摘要

In an example, a method for image processing may include inputting a first pixel value corresponding to a first pixel of an image into a LUT. The LUT may map one or more LUT input values to one or more LUT output values. The first pixel value may correspond to a first LUT input value that maps to a first LUT output value in the LUT. The first pixel may include one or more pixel values. The method may include generating a noise value for the first LUT input value. The method may include generating a first interpolated LUT output value for the first LUT input value based on the noise value. The method may include transforming the image into a transformed image using the first interpolated LUT output value.

1. A method comprising:
inputting, by a processing unit, a first pixel value corresponding to a first pixel of an image into a Look Up Table (LUT), wherein the LUT maps one or more LUT input values to one or more LUT output values, and wherein the first pixel value corresponds to a first LUT input value that maps to a first LUT output value in the LUT; applying noise to the first LUT input value to generate a noise-modified first LUT input value, wherein the noise is represented by a noise value; generating, by the processing unit, a first interpolated LUT output value for the first LUT input value based on the noise-modified first LUT input value; and transforming, by the processing unit, the image into a transformed image using the first interpolated LUT output value.
