Latest Patents

Among his latest patents, Zeng has developed methods and systems for transmitting digital images. These embodiments comprise techniques for communicating a recipient-selected customization of a digital image using an index file. The index file associates a customization characteristic with the segments of the digital image required to construct a customized image that exhibits the desired customization characteristic. Another notable patent focuses on a method for removing ringing artifacts from locations near dominant edges of an image reconstructed after compression. This method involves decomposing the image into blocks small enough to contain only one significant edge. The significant edge is tested to determine if it is a dominant edge of the image. If no dominant edge is present, the block remains unprocessed. In the remaining blocks, the exact pixels that include the dominant edges are output without filtering. The direction of the dominant edges is inferred, and the remaining pixels are filtered using a directional de-ringing filter, which has a main direction that is perpendicular to the edge direction, effectively addressing the inherent direction of the ringing artifacts.
