Abstract:
Embodiments of a computer-implemented method for thin-line enhancement in electronic images are disclosed. The methods include receiving a halftone image comprising multiple pixels, and associating a predefined kernel with at least a portion of the halftone image. The kernel includes multiple check cells and a processing cell, each capable of being toggled between an active state and an inactive state; detecting a state of each of the pixels in the neighborhood of an inactive pixel associated with the processing cell based on one or more predetermined rules being applied to the kernel, wherein the inactive pixel is in communication with a contiguous set of active pixels; and selectively activating the inactive pixel by activating the processing cell based on the predetermined rules, provided the inactive pixel upon being activated is separated from a neighboring active pixel.
