Content adaptive deblocking during video encoding and decoding
Disclosed herein are exemplary embodiments of methods, apparatus, and systems for performing content-adaptive deblocking to improve the visual quality of video images compressed using block-based motion-predictive video coding. For instance, in certain embodiments of the disclosed technology, edge information is obtained using global orientation energy edge detection (“OEED”) techniques on an initially deblocked image. OEED detection can provide a robust partition of local directional features (“LDFs”). For a local directional feature detected in the partition, a directional deblocking filter having an orientation corresponding to the orientation of the LDF can be used. The selected filter can have a filter orientation and activation thresholds that better preserve image details while reducing blocking artifacts. In certain embodiments, for a consecutive non-LDF region, extra smoothing can be imposed to suppress the visually severe blocking artifacts. |

Copy identification with ultraviolet light exposure
An original has a first pattern on and a second pattern, and the first pattern and the second pattern include relatively lighter markings within a relatively darker background. The relatively lighter markings appear at a first spacing interval in the first pattern, and at a larger second spacing interval in the second pattern. The first pattern and the second pattern cover and equally block a region of the original from reflecting ultraviolet light. A scanner is only capable of detecting patterns of markings having a spacing interval larger than the first spacing interval, which causes a copy of the original to not include the relatively lighter markings appearing at the first spacing interval. Thus, the copy lacks markings at locations corresponding to where the relatively lighter markings appear at the first spacing interval in the original. The copy reflects the ultraviolet light more where the copy lacks markings. |

Selective bypassing of daisy-chained network devices
Apparatus and associated methods relate to selectively bypassing a daisy-chained network device based on a timing of a series of reset signals. The daisy-chained network device is bypassed if an elapsed time from a last of the reset signals of the series is longer than a predetermined time period. While no interval between adjacent reset signals of the series exceeds the predetermined time period, the daisy-chained network device is not bypassed. In some embodiments, the daisy-chained network device generates the series of reset signals. If the daisy-chained network device fails to generate a next reset signal within the predetermined time period as measured from a previous reset signal, the daisy-chained network device is bypassed. If the daisy-chained network device loses power, it will be bypassed as the reset signals will not be generated, but if the daisy-chained network device regains power, it can be reinserted into the network daisy-chain. |
