This paper presents an anchor-pair network for crowded human detection, which can overcome and solve the difficulties caused by occlusion in crowded scenes. Specifically, we use a function-aware network structure to extract more distinctive and discriminative features for head and full-body respectively, and then a CNN module is also exploited to fuse the features by learning the correlations between head and full-body to reduce crowd errors. Meanwhile, a novel paired form for anchors, denoted as anchor-pair, is proposed to estimate the head regions and full-body regions simultaneously. Furthermore, a new ingenious Joint-NMS is introduced to perform on the detected head and full-body box pairs, which produces significant performance improvement in heavily occluded scenarios at tiny computational cost. Our anchor-pair network achieves a state-of-the-art result on the CrowdHuman dataset which reduces the MR-2 to 55.43%, achieving 11.59% relative improvement over our dataset baseline.

Background/objective: The first line treatment for obstructive sleep apnea (OSA) is nasal continuous positive airway pressure (nCPAP), for which a variety of masks are available. While nasal masks (NM) are the first choice; oronasal masks (ONM) are also frequently used to prevent mouth dryness resulting from mouth opening. Our cross-sectional, prospective, randomized, un-blinded study addressed the efficacy of wearing an oral shield in addition to NM in preventing mouth leakage Methods: Patients with OSA and established therapy using NM and complaining about mouth dryness (n = 29) underwent three polysomnographies (PSGs) using NM, ONM or a nose mask in combination with an oral shield (NMS). Mask leakage was continuously documented and objective sleep quality was assessed. Results: There were significant differences in the apnea-hypopnea-index (AHI) between ONM (8.5/h; SD 6,7) and NM/nasal mask combined with oral shield device (NMS) (2.6/h; SD 2,3; 2.7/h; SD 2,6) (p < 0,05) as well as in leakage [ONM (39.7 l/min SD 12,4); NM (34.6 l/min SD 9,4); NMS (33.1 l/min SD 9,6)] (p = 0.011). Furthermore, analysis of sleep quality (NREM3) favored NM and NMS over ONM (p = 0.02). There were no significant differences between NM and NMS in any objective outcome. Conclusions: Our data consistently confirmed the NM as the first choice for continuous positive airway pressure (CPAP) therapy of OSA. Notably, we demonstrated a high potential of the oral shield for patients with mouth opening to achieve additional comfort and thereby possibly compliance, without affecting nCPAP therapy effectiveness.
