A survey of face recognition techniques under occlusion [PDF]

open access: yesarXiv, 2020
The limited capacity to recognize faces under occlusions is a long-standing problem that presents a unique challenge for face recognition systems and even for humans. The problem regarding occlusion is less covered by research when compared to other challenges such as pose variation, different expressions, etc.

Preliminary investigation of the effects of long-term dietary intake of genistein and daidzein on hepatic histopathology and biochemistry in domestic cats (Felis catus) [PDF]

open access: yes, 2012
Dietary isoflavones have been hypothesised to play a role in hepatic veno-occlusive disease in captive exotic felids, although empirical evidence is lacking. This study aimed to investigate the effect of long-term (>1 year) dietary genistein and daidzein

Prevalence of peripheral arterial occlusive disease in patients referred to a tertiary care hospital in Salvador, Bahia, Brazil, for coronary angiography

open access: yesBrazilian Journal of Medical and Biological Research, 2008
The presence of peripheral arterial occlusive disease increases the morbidity and mortality of patients with coronary artery disease. The objective of the present study was to calculate the prevalence of peripheral arterial occlusive disease in patients ...

Perforating artery flow velocity and pulsatility in patients with carotid occlusive disease. A 7 tesla MRI study

open access: yesCerebral Circulation - Cognition and Behavior, 2022
Patients with carotid occlusive disease express altered hemodynamics in the post-occlusive vasculature and lesions commonly attributed to cerebral small vessel disease (SVD). We addressed the question if cerebral perforating artery flow measures, using a

Liver necrosis following cholecystectomy in sickle cell disease

open access: yesClinical Case Reports, 2020
Postoperative vaso‐occlusive disease may be a life‐threatening condition in patients affected by sickle cell disease, necessitating sometimes liver transplantation. After laparoscopic cholecystectomy, liver necrosis is usually secondary to intraoperative

Quantitative and Qualitative Analysis of Dynamic Cavernosographies in Erectile Dysfunction due to Venous Leakage [PDF]

open access: yes, 1989
Of 521 patients with erectile dysfunction in whom a multidisciplinary approach was used, 145 (27.8%) showed venous leakage as (concomitant) etiology of the impotence in dynamic cavernosography.

MirrorFlow: Exploiting Symmetries in Joint Optical Flow and Occlusion Estimation [PDF]

open access: yesarXiv, 2017
Optical flow estimation is one of the most studied problems in computer vision, yet recent benchmark datasets continue to reveal problem areas of today's approaches. Occlusions have remained one of the key challenges. In this paper, we propose a symmetric optical flow method to address the well-known chicken-and-egg relation between optical flow and ...

Medical therapy, percutaneous coronary intervention and prognosis in patients with chronic total occlusions [PDF]

open access: yes, 2015
Objective There is little published data reporting outcomes for those found to have a chronic total coronary occlusion (CTO) that is electively treated medically versus those treated by percutaneous coronary intervention (PCI).
