Title: A Blind Digital Watermarking Method for Omni-directional Images using Feature Points
Inventor: ISEUL KANG
IPC: G06T1/00
Filed: 2018-02-01
Abstract: The present invention relates to a method of performing blind digital watermarking for omnidirectional image by using feature points, capable of assuming that the owners of original photographed images can be different; inserting different watermark data into each of the original images; and extracting a watermark from a projected image servicing an omnidirectional image. The method includes: a step (a) of obtaining a plurality of original images for an omnidirectional image; a step (b) of selecting an image part to be watermarked by selecting a part, which is not going to be used for stitching, from each of the original images; a step (c) of extracting feature points from the selected image part; a step (d) of selecting an area around the feature points as a DW target area; a step (e) of selecting a position, into which an actual WM is inserted, from the DW target area; a step (f) of inserting the watermark into the selected insertion position; and a step (g) of reversely converting a result image with the watermark inserted therein. According to the watermarking method, since feature points of an area not used for stitching are used and data around the feature points are used as DW positions, strength against the distortion of an image, which occurs during the generation of an omnidirectional image, can be formed, and additionally, sufficient strength against JPEG compression attacks can be formed.

Title: Method for impedance compensation in printed circuit boards
Inventor: BECKER ANDY
IPC: H05K1/11
Filed: 2018-02-08
Abstract: Various structures forming a communication path on a printed circuit board can generate several undesired effects, especially when a high frequency signal is considered. Non-functional pads generated during a manufacturing process have a possibility to generate the undesired effect. However, when the overall collections of the non-functional pads are carefully composed, an optimized communication path can be formed. More specifically, a high frequency characteristic of the communication path can be optimized by selectively removing some collections of the non-functional pads. A method for adjusting an impedance property of a printed circuit board during manufacturing comprises the following steps of: receiving a substrate layout; developing a model; determining electrical impedance; changing the substrate layout; and manufacturing a printed circuit board.
