Abstract
Several embodiments of systems and methods are disclosed that create iso-perceptible image data from input image data. Such iso-perceptible image data may be created from Just-Noticeable-Difference (JND) modeling that leverages models from the Human Visual System (HVS). From a set of iso-perceptible image data set, an output image data may be selected, such that the chosen output image data has a less power and/or energy requirement to render than the input image data. Further, the output image data may have a substantially lower power and/or energy requirement than the set of iso-perceptible image data.
Claims16
A system for image processing, said system comprising:
- a color quantizer module, said color quantizer module capable of color quantizing input image data;
- a just-noticeable-difference (JND) module, said JND module capable of creating an intermediate set of image data that is substantially iso-perceptible from said color quantized input image data;
- and
- a power reducing module, said power reducing module capable of selecting an output image data from said intermediate set of image data, such that said output image data comprises a lower power requirement for rendering said output image data as compared with said input image data.
A method for image processing input image data and creating output image data, said output image data substantially iso-perceptible to said input data and said output image data comprising a lower power requirement for rendering than said input image data, the steps of said method comprising:
- color quantizing input image data;
- creating a just-noticeable-difference (JND) set of image data, said JND set of image data being substantially iso-perceptible to said input image data;
- and
- selecting an output image data, said output image data chosen among said JND set of image data and said output image data comprising a lower power requirement for rendering than said input image data.
