Abstract
A method, system and data structure for providing a 3+1 layer MRC image, including a black text layer. The black text layer includes pixel data corresponding to black text in an image and may be assigned a predetermined value for the color of black. According to one or more embodiments, using thresholding processing along with various morphological operations, the black text layer may be generated.
Claims22
A method for processing image data, comprising:
- providing input image data;
- segmenting the input image data to generate:
- a background layer representing the background attributes of an image;
- a selector layer for identifying one or more foreground attributes of the image not included in the background layer;
- and
- a foreground layer representing the foreground attributes of the image;
- generating a black text layer comprising pixel data representing black text in the input image data;
- assigning the black text pixel data a predetermined value for the color black;
- and
- integrating the background layer, the selector layer, the foreground layer, and the black text layer into a data structure having machine-readable instructions that may be stored in a memory device.
A system for processing image data comprising:
- an image segmentor configured to receive image data and to generate
- a background layer representing the background attributes of an image;
- a selector layer for identifying one or more foreground attributes of the image not included in the background layer;
- and
- a foreground layer representing the foreground attributes of the image;
- a black text layer generating unit configured to determine pixel data representing black text in the input image data and to assign a predetermined color of black to the black text pixel data;
- and
- an integrating unit configured to integrate the background layer, the selector layer, the foreground layer, and the black text layer into a data structure having machine-readable instructions that may be stored in an memory device.
A data structure having machine-readable information stored in a memory device that when implemented by a processor render an image, the data structure comprising:
- a background layer representing the background attributes of an image;
- a selector layer for identifying one or more foreground attributes of the image not included in the background layer;
- a foreground layer representing the foreground attributes of the image;
- and
- a black text layer comprising pixel data representing black text in the image, wherein the black text pixel data corresponds to a predetermined value for the color black.
