There are many methods to extract moving objects in a scene using background subtraction. However, most methods assume that there are no moving objects except intruders in the observing space. In this paper, we propose the iterative optimal projection method to estimate a varied background in real time from a dynamic scene with intruders. At first,(More)
Statins have a variety of myotoxic effects and can trigger the development of inflammatory myopathies or myasthenia gravis (MG) mediated by immunomodulatory properties. Autoantibodies to 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) have been identified in patients with statin-associated myopathy. The purpose of the present study is to develop an(More)
The aromatic beta-carboline norharmane was determined in workers, nymphs, and ergatoids of Reticulitermes speratus (Kolbe) (Isoptera: Rhinotermitidae) by gas chromatography/mass spectrometry. Norharmane levels in workers, nymphs, and ergatoids collected in May (approximately 4.3 ng/termite) were higher than those in November (approximately 0.2 ng/termite).(More)
[Purpose] This study investigated the relationship between lumbar pelvic rhythm and the physical characteristics of stoop lifting. [Subjects and Methods] Participants performed a stoop lifting task under two conditions: with and without load. We assessed the lumbar kyphosis and sacral inclination angles using the SpinalMouse(®) system, as well as hamstring(More)
The aromatic-carboline norharmane, which is located in the fat body of Reticulitermes speratus, stimulated the activity of juvenile hormone epoxide hydrolase (JHEH) of larva, ergatoid, and nymphoid homogenates. JHEH activity of ergatoid (16.67 ± 1.30 μU/termite) and nymphoid (20.94 ± 1.64 μU/termite) homogenates fortified with 0.1 mM norharmane was(More)
In computer vision, background subtraction method is widely used to extract a changing region in a scene. However, it is difficult to simply apply this method to a scene with moving background object, because such object may be extracted as a changing region. Therefore, a method has been proposed to estimate both current background image and occluding(More)
