Abstract
Official abstract text for this publication.
A binary image downsampling method, including the steps of generating a gray-scale image from a binary image having a background and one or more foreground portions, locating skeleton pixels in the one or more foreground portions, manipulating values of certain foreground pixels in the gray-scale image such that the differences between the values of the skeleton pixels and the background pixels become more significant, downsampling the gray-scale image with the manipulated values of the certain foreground pixels, and generating a downsampled binary image from the downsampled gray-scale image.
First claim
Opening claim text (preview).
What is claimed is: 1. A binary image downsampling method, comprising: generating a gray-scale image from a binary image having a background and one or more foreground portions; locating skeleton pixels of the gray-scale image, which are pixels corresponding to skeletons of the binary image in the one or more foreground portions; manipulating values of certain foreground pixels in the gray-scale image including at least the skeleton pixels, by changing their original pixel val…
