Abstract
An apparatus usable in an image encoding and/or decoding system includes a segmentation unit to convert a first image of a first resolution into a second image of a second resolution, to segment the second image of the second resolution with one or more blocks of a binary mask layer having a foreground and a background, and to convert the segmented second image into a third image of a third resolution as a segmented image.
Claims26
An apparatus usable in an image encoding and decoding system, comprising:
- a converting unit to convert a first image of a first resolution into a second image of a second resolution lower than the first resolution;
- a segmentation unit to divide the second image into blocks and segment the second image to generate a binary mask layer having a foreground and a background;
- and
- a refining unit to use the first image to convert the segmented second image into a segmented third image having a third resolution higher than the second resolution,
- wherein the third resolution is the same as the first resolution.
An apparatus usable in an image encoding and decoding system, comprising:
- a converting unit to receive a first image having a first resolution and to generate a second image having a second resolution that is less than the first resolution;
- a segmentation unit to divide the second image into blocks and segment the second image to generate a binary mask layer having a foreground and a background;
- and
- a refining unit to generate a third image from the segmented second image by using the first image, the third image having a third resolution that is greater than the second resolution,
- wherein the third resolution is the same as the first resolution.
An apparatus usable in an image encoding and decoding system, comprising:
- a converting unit to convert a first image of a first resolution into a second image of a second resolution lower than the first resolution;
- a segmenting unit to divide the second image into blocks and segment the second image to generate a binary mask layer having a foreground and a background;
- a refining unit to use the first image to convert the segmented second image into a segmented third image of a third resolution higher than the second resolution;
- an encoding unit to encode the segmented third image as an output image signal;
- a decoding unit to decode the output image signal as a print image signal;
- and
- a printing unit to print the print image signal on a printing medium,
- wherein the third resolution is the same as the first resolution.
