In this paper, we propose a new single-image dehazing method. The proposed method constructs color ellipsoids that are statistically fitted to haze pixel clusters in RGB space and then calculates the transmission values through color ellipsoid geometry. The transmission values generated by the proposed method maximize the contrast of dehazed pixels, while preventing over-saturated pixels. The values are also statistically robust because they are calculated from the averages of the haze pixel values. Furthermore, rather than apply a highly complex refinement process to reduce halo or unnatural artifacts, we embed a fuzzy segmentation process into the construction of the color ellipsoid so that the proposed method simultaneously executes the transmission calculation and the refinement process. The results of an experimental performance evaluation verify that compared with prevailing dehazing methods the proposed method performs effectively across a wide range of haze and noise levels without causing any visible artifacts. Moreover, the relatively low complexity of the proposed method will facilitate its real-time applications.

This paper shares lessons learned in moving toward change when addressing an EJ community's health challenges.

Context: Research has linked adverse childhood experiences (ACEs) with chronic disease in adults and diminished life span. Adverse biological embedding of ACEs potentially occurs through inflammatory mechanisms; inflammatory marker alterations are identified as candidate biomarkers for mediating health consequences. Lifestyle practices of residents of California's Loma Linda Blue Zone, one of five worldwide longevity hotspots, may provide insight into inflammation remediation and chronic disease prevention. Little research has been done on centenarians' early-life experiences or on ACEs in a longevity community.Objective: To interview centenarians and seniors in this region regarding their childhood experiences to inform chronic disease prevention frameworks.Design: Qualitative study of Loma Linda Blue Zone community members. Childhood exposures and practices were assessed using focus groups and semistructured key informant interviews, with open-ended questions on general hardships and ACEs and supplemented with lifestyle and resiliency factor questions. Data were audiorecorded and transcribed. Integrative grounded theory methods guided coding and theming.Main Outcome Measures: Exposure to ACEs and practice of resiliency factors. Results: Participants (7 centenarians and 29 seniors) reported exposure to multiple ACEs (domains: Economic deprivation, family dysfunction, and community violence). Community members reported practicing resiliency factors, each with anti-inflammatory properties suggesting mitigation of ACE-related toxic stress.Conclusion: This is one of the first studies of its kind to identify a community of resilient members despite their tremendous burden of ACEs. Embedding the identified resiliency factors into chronic disease prevention frameworks has potential for mitigating systemic inflammation, alleviating chronic disease burden, and promoting a culture of health.

We have developed a video processing method that achieves human perceptual visual quality-oriented video coding. The patterns of moving objects are modeled by considering the limited human capacity for spatial-temporal resolution and the visual sensory memory together, and an online moving pattern classifier is devised by using the Hedge algorithm. The moving pattern classifier is embedded in the existing visual saliency with the purpose of providing a human perceptual video quality saliency model. In order to apply the developed saliency model to video coding, the conventional foveation filtering method is extended. The proposed foveation filter can smooth and enhance the video signals locally, in conformance with the developed saliency model, without causing any artifacts. The performance evaluation results confirm that the proposed video processing method shows reliable improvements in the perceptual quality for various sequences and at various bandwidths, compared to existing saliency-based video coding methods.

Background and Purpose: Oral health is often related to other medical conditions. This study investigated the knowledge and opinions of California physicians, dentists, pharmacists, and advanced practice registered nurses (APRNs) regarding the interface between oral and overall health and their suggestions for strengthening this interface. Methods: A survey packet was mailed to randomly-selected California healthcare providers in Winter 2015. Twenty five-point Likert-type questions were used to measure the providers’ knowledge and opinions of the oral and overall health interface. Results: Sixtytwo physicians, 117 dentists, 136 pharmacists, and 289 Advanced Practice Registered Nurses (APRNs) responded (total N= 604). A majority of all health professionals agreed/strongly agreed that oral health topics received little attention in the education of non-dental health professionals (n=499, 82.6%), and that the dental discipline remains relatively segregated from other healthcare disciplines (n=500, 82.8%). Dentists and APRNs were more likely to agree/agree strongly that the inadvertent prescribing of medications that can have xerostomic effects without considering their oral health implications is a major problem. Conclusion: There is a need for more inter-professional collaboration by all primary care providers in managing the patients’ oral and overall health, as well as more oral health education and training for all non-dental health professionals.
