Abstract
Embodiments of the present disclosure provide a method comprising accessing a first pixel that is neighboring to a second pixel of an image, the first pixel including a plurality of color fields, each color field of the plurality of color fields associated with a respective color plane, wherein the second pixel is to be processed as a target pixel; quantizing the plurality of color fields to generate a corresponding plurality of quantized color fields, wherein said quantizing the plurality of color fields is based on a contribution of individual color planes of the plurality of color planes towards an intensity of the image; and processing the target pixel based at least in part on the plurality of quantized color fields. Other embodiments are also described and claimed.
Claims22
A method comprising:
- accessing a first pixel that is neighboring to a second pixel of an image, the first pixel including a plurality of color fields, each color field of the plurality of color fields associated with a respective color plane, wherein the second pixel is to be processed as a target pixel;
- quantizing the plurality of color fields to generate a corresponding plurality of quantized color fields, wherein said quantizing the plurality of color fields is based on a contribution of individual color planes of the plurality of color planes towards an intensity of the image;
- and
- processing the target pixel based at least in part on the plurality of quantized color fields.
A system-on-chip (SOC) comprising:
- a pixel window control module configured to form a pixel window around a target pixel of an image, the pixel window comprising a plurality of neighboring pixels including a pixel, the pixel including a plurality of color fields, each color field associated with corresponding color plane;
- a quantization module configured to
- determine that the plurality of color fields are not quantized, and
- based on determining that the plurality of color fields are not quantized, quantize the plurality of color fields to generate a corresponding plurality of quantized color fields, wherein said quantizing the plurality of color fields is based on a contribution of individual color planes of the plurality of color planes towards an intensity of the image;
- and
- a target pixel processing module configured to process the target pixel based at least in part on the plurality of quantized color fields.
A method comprising:
- forming a pixel window around a pixel of an image, the pixel window comprising a plurality of neighboring pixels of the pixel, each neighboring pixel of the plurality of neighboring pixels comprising a plurality of color fields, each color field associated with a corresponding color plane;
- for each of one or more neighboring pixels of the plurality of neighboring pixels, quantizing the plurality of color fields to generate a corresponding plurality of quantized color fields based on a contribution of individual color planes of the plurality of color planes towards an intensity of the image;
- and
- processing the pixel based at least in part on the plurality of quantized color fields of the one or more neighboring pixels.
