Simultaneous contrast based picture quality improvement for power saving

1 . A computer-implemented method comprising:

receiving an input image associated with a media content item;

performing gradient detection to determine one or more outlines for the input image; and

enhancing, based on the one or more outlines, a perceived contrast associated with the input image, wherein enhancing the perceived contrast utilizes a local median-based patch processing to adjust one or more image attributes in an output image.

2 . The method of claim 1 , further comprising:

maintaining or reducing power consumption of a display device while enhancing the perceived contrast.

3 . The method of claim 2 , further comprising:

providing a model for simultaneous contrast for picture quality improvement based on outline-based enhancement and final contrast correction, while preserving or reducing power consumption of the display device.

4 . The method of claim 1 , wherein enhancing perceived contrast associated with the input image is based on a Bartleson-Breneman (BB) effect.

5 . The method of claim 4 , wherein utilizing the local median-based patch processing improves the BB effect in the output image.

6 . The method of claim 1 , further comprising:

computing a brightness map for the input image.

7 . The method of claim 6 , further comprising:

combining the brightness map with the input image to enhance a foreground of the input image relative to a background of the input image.

8 . A non-transitory processor-readable medium that includes a program that when executed by a processor provides enhancement of perceived contrast associated with an input image, comprising:

receiving, by the processor, an input image associated with a media content item;

performing, by the processor, gradient detection to determine one or more outlines for the input image; and

enhancing, by the processor, based on the one or more outlines, a perceived contrast associated with the input image, wherein enhancing the perceived contrast utilizes a local median-based patch processing to adjust one or more image attributes in an output image.

9 . The non-transitory processor-readable medium of claim 8 , further comprising:

maintaining or reducing power consumption of a display device while enhancing the perceived contrast.

10 . The non-transitory processor-readable medium of claim 9 , further comprising:

providing a model for simultaneous contrast for picture quality improvement based on outline-based enhancement and final contrast correction, while preserving or reducing power consumption of the display device.

11 . The non-transitory processor-readable medium of claim 8 , wherein enhancing perceived contrast associated with the input image is based on a Bartleson-Breneman (BB) effect.

12 . The non-transitory processor-readable medium of claim 11 , wherein utilizing the local median-based patch processing improves the BB effect in the output image.

13 . The non-transitory processor-readable medium of claim 8 , further comprising:

computing a brightness map for the input image.

14 . The non-transitory processor-readable medium of claim 13 , further comprising:

combining the brightness map with the input image to enhance a foreground of the input image relative to a background of the input image.

15 . An apparatus comprising:

a memory storing instructions; and

at least one processor executes the instructions including a process configured to:

receive an input image associated with a media content item;

perform gradient detection to determine one or more outlines for the input image; and

enhance, based on the one or more outlines, a perceived contrast associated with the input image, wherein the process enhances the perceived contrast utilizing a local median-based patch processing to adjust one or more image attributes in an output image.

16 . The apparatus of claim 15 , wherein the process is further configured to:

maintain or reduce power consumption of a display device while enhancing the perceived contrast.

17 . The apparatus of claim 15 , wherein the process is further configured to:

provide a model for simultaneous contrast for picture quality improvement based on outline-based enhancement and final contrast correction, while preserving or reducing power consumption of the display device.

18 . The apparatus of claim 15 , wherein enhancing perceived contrast associated with the input image is based on a Bartleson-Breneman (BB) effect.

19 . The apparatus of claim 18 , wherein utilizing the local median-based patch processing improves the BB effect in the output image.

20 . The apparatus of claim 15 , wherein the process is further configured to:

compute a brightness map for the input image; and

combine the brightness map with the input image to enhance a foreground of the input image relative to a background of the input image.
