Latest Patents

Jewitt's latest patents include a "System and method for a robust de-screening filter." This invention provides a method and apparatus for de-screening a halftone image, allowing for the recovery of an approximation of the original image. The method involves performing a screen conversion filter on a scanned representation of the halftone image to produce an intermediate image, followed by a line smoothing filter to achieve an approximation of the original image. An alternate embodiment utilizes a single convolution filter to produce a similar approximation.

Another notable patent is the "Error diffusion method and apparatus." This invention addresses the issue of error diffusion caused by quantizing each pixel within an image. The method includes adding a first error term to the original greyscale value of a pixel, comparing it with a threshold, and distributing the second error term to neighboring pixels using a linear phase filter algorithm. This process is repeated for each pixel within the image, enhancing the overall image quality.
