OBJECTIVE The management of antenatally diagnosed ureteropelvic junction obstruction (PUJO) is controversial. Here, we present our experience over a period of 13 years and discuss our management protocol. MATERIALS AND METHODS We reviewed the files of 234 patients with antenatally diagnosed congenital hydronephrosis due to PUJO. Management was tailored to(More)
The work on support for higher bit depths and 4:2:2 as well as 4:4:4 chroma sampling formats for the High Efficiency Video Coding (HEVC) standard is currently being conducted under the term Range Extensions (RExt). A technique that exploits the correlation between residual color components in 4:4:4 chroma sampling format, also referred to as Cross-Component(More)
This paper focuses on the detection of freezing artifacts that could occur in the navigation system of the car during field tests. Knowing that the motion in the navigation system could also stop when the car stops, it is crucial to differentiate between this situation and a real freezing artifact. We propose an algorithm that reliably detects map jumps(More)
With Version 2 of the high-efficiency video coding standard, a new compression efficiency tool targeting redundancies among color components is specified for all 4:4:4 profiles, and referred to as cross-component prediction (CCP). This paper describes and analyses two additional extensions to the specified CCP variant. In the first extension, an additional(More)
