    In this paper we present a method for real-time detection of human fall from video for support of elderly people living alone in their homes. The detection algorithm has four steps: background estimation, extraction of moving objects, motion feature extraction, and fall detection. The detection is based on features that quantify dynamics of human motion and body orientation. The algorithms are implemented in C++ using the OpenCV library. The method is tested using a single camera and 20 test video recordings showing typical fall scenarios and regular household behaviour. The experimental results show 90% of human fall detection accuracy

    International audienceAbstract Background Optimal oxygen targets in patients resuscitated after cardiac arrest are uncertain. The primary aim of this study was to describe the values of partial pressure of oxygen values (PaO 2 ) and the episodes of hypoxemia and hyperoxemia occurring within the first 72¬†h of mechanical ventilation in out of hospital cardiac arrest (OHCA) patients. The secondary aim was to evaluate the association of PaO 2 with patients‚Äô outcome. Methods Preplanned secondary analysis of the targeted hypothermia versus targeted normothermia after OHCA (TTM2) trial. Arterial blood gases values were collected from randomization every 4¬†h for the first 32¬†h, and then, every 8¬†h until day 3. Hypoxemia was defined as PaO 2 ‚ÄČ300¬†mmHg. Mortality and poor neurological outcome (defined according to modified Rankin scale) were collected at 6¬†months. Results 1418 patients were included in the analysis. The mean age was 64‚ÄȬĪ‚ÄČ14¬†years, and 292 patients (20.6%) were female. 24.9% of patients had at least one episode of hypoxemia, and 7.6% of patients had at least one episode of severe hyperoxemia. Both hypoxemia and hyperoxemia were independently associated with 6-month mortality, but not with poor neurological outcome. The best cutoff point associated with 6-month mortality for hypoxemia was 69¬†mmHg (Risk Ratio, RR‚ÄČ=‚ÄČ1.009, 95% CI 0.93‚Äď1.09), and for hyperoxemia was 195¬†mmHg (RR‚ÄČ=‚ÄČ1.006, 95% CI 0.95‚Äď1.06). The time exposure, i.e., the area under the curve (PaO 2 -AUC), for hyperoxemia was significantly associated with mortality ( p =‚ÄČ0.003). Conclusions In OHCA patients, both hypoxemia and hyperoxemia are associated with 6-months mortality, with an effect mediated by the timing exposure to high values of oxygen. Precise titration of oxygen levels should be considered in this group of patients. Trial registration : clinicaltrials.gov NCT02908308 , Registered September 20, 2016
