She has made significant contributions to the field of video image processing, holding 2 patents that showcase her innovative techniques. Her work primarily focuses on enhancing the quality of video images, which is crucial in today's digital communication landscape.

Latest Patents

One of her latest patents is titled "Method for reducing line width variations in bilevel video images." This invention addresses the issue of line width variations that occur due to undersampling of original images in teleconferencing systems. The method involves writing bilevel data into two-dimensional storage arrays and analyzing the data to classify black horizontal and vertical runs. By overwriting specific pels with gray pels based on run length, the method effectively reduces variations in line width.

Another significant patent by Lasher is "Enhancement of video images by selective introduction of gray-scale pels." This technique enhances displayed images originally stored at a density of 1 data bit per pel. The method scans the stored data to locate unit steps in binary values and uses the distances from these steps to assign 4-bit gray scale values to adjacent pels. This selective introduction of intermediate gray scale values improves the visual quality of the displayed image.
