摘要： The establishment and control of oxygen levels in packs of oxygen-sensitive food products such as cheese is imperative in order to maintain product quality over a determined shelf life. Oxygen sensors quantify oxygen concentrations within packaging using a reversible optical measurement process, and this non-destructive nature ensures the entire supply chain can be monitored and can assist in pinpointing negative issues pertaining to product packaging. This study was carried out in a commercial cheese packaging plant and involved the insertion of 768 sensors into 384 flow-wrapped cheese packs (two sensors per pack) that were flushed with 100% carbon dioxide prior to sealing. The cheese blocks were randomly assigned to two different storage groups to assess the effects of package quality, packaging process efficiency, and handling and distribution on package containment. Results demonstrated that oxygen levels increased in both experimental groups examined over the 30-day assessment period. The group subjected to a simulated industrial distribution route and handling procedures of commercial retailed cheese exhibited the highest level of oxygen detected on every day examined and experienced the highest rate of package failure. The study concluded that fluctuating storage conditions, product movement associated with distribution activities, and the possible presence of cheese-derived contaminants such as calcium lactate crystals were chief contributors to package failure.

关键词： Depth sensors   gesture recognition   multisensor   occlusion   pose estimation   user evaluation  

摘要： Recent advances in smart sensor technology and computer vision techniques have made the tracking of unmarked human hand and finger movements possible with high accuracy and at sampling rates of over 120 Hz. However, these new sensors also present challenges for real-time gesture recognition due to the frequent occlusion of fingers by other parts of the hand. We present a novel multisensor technique that improves the pose estimation accuracy during real-time computer vision gesture recognition. A classifier is trained offline, using a premeasured artificial hand, to learn which hand positions and orientations are likely to be associated with higher pose estimation error. During run-time, our algorithm uses the prebuilt classifier to select the best sensor-generated skeletal pose at each time step, which leads to a fused sequence of optimal poses over time. The artificial hand used to establish the ground truth is configured in a number of commonly used hand poses such as pinches and taps. Experimental results demonstrate that this new technique can reduce total pose estimation error by over 30% compared with using a single sensor, while still maintaining real-time performance. Our evaluations also demonstrate that our approach significantly outperforms many other alternative approaches such as weighted averaging of hand poses. An analysis of our classifier performance shows that the offline training time is insignificant, and our configuration achieves about 90.8% optimality for the dataset used. Our method effectively increases the robustness of touchless display interactions, especially in high-occlusion situations by analyzing skeletal poses from multiple views.
