Migratory Bird Detection Based on Haar-like Feature
Mutsuhiro Terauchi,Sung-Hoon Choi,Hyuk Park,Hee-Cheol Kim,Bok-Suk Shin 한국정보통신학회 2018 2016 INTERNATIONAL CONFERENCE Vol.10 No.1
Since migrating birds can spread the Avian Influenza (AI), AI expansion can be reduced or blocked by establishing a comprehensive surveillance system on the bird migration pattern by observing and tracking their migration paths and habitats. It is necessary to develop technological approach to observe and track the migrating birds. We propose a method for detecting migratory birds toward observation by using Haarlike features and a feature map. The process of using Haar-like feature can classify groups between adjacent dark and bright from a river scene with floating migratory birds. This paper focuses on success rate of detection of migratory bird or group of migratory birds by combining optimization algorithm with a geometrical feature map. We also present the experimental results on bird detection, by comparing previously achieved results.

Background/Aims: The clinical impact of single-stage endoscopic stone extraction by endoscopic retrograde cholangiopancreatography(ERCP) and cholecystectomy during the same hospitalization remains elusive. This study aimed to determine the effcacy and safety ofsingle-stage ERCP and cholecystectomy during the same hospitalization in patients with cholangitis. Methods: We retrospectively reviewed the medical records of 166 patients who underwent ERCP for mild to moderate cholangitis dueto choledocholithiasis secondary to cholecystolithiasis from 2012 to 2016. Results: Complete stone extraction was accomplished in 92% of patients (152/166) at the first ERCP. Among 152 patients whounderwent complete stone extraction, cholecystectomy was scheduled for 119 patients (78%). Cholecystectomy was performed duringthe same hospitalization in 89% of patients (106/119). We compared two groups of patients: those who underwent cholecystectomyduring the same hospitalization (n=106) and those who underwent cholecystectomy during a subsequent hospitalization (n=13). In thedelayed group, cholecystectomy was performed about three months after the first ERCP. There were no significant differences betweenthe groups in terms of operative time, rate of postoperative complications, and interval from cholecystectomy to discharge. Conclusions: Single-stage endoscopic stone extraction is recommended in patients with mild to moderate acute cholangitis due tocholedocholithiasis. The combination of endoscopic stone extraction and cholecystectomy during the same hospitalization is safe andfeasible.

The relationship between riding comfort and the properties of flexible polyurethane foam used in car seats was quantitatively illustrated through vibration experiments with humans sitting in car seats, which were vertically shaken by vibrator. Riding comfort was estimated according to SD (Semantic Differential)-method using questionnaire, and was analyzed with a factor analysis which demonstrated the principal factors of riding comfort. At the same time, riding comfort was related to the properties of the flexible polyurethane foam with coefficients of correlation. It was also related to the behaviour of its vibration of humans sitting in the seats. As a result, it was demonstrated that the relationship between riding comfort and the flexible polyurethane foam properties varies according to the frequency of the vibration shaking the human sitting in the seat. and it was demonstrated that the frequency dependence of the relationship is strongly affected by the physical changes of the vibration modes of the human-seat vibration system.

We have developed a new HD-2700 (Hitachi High-Technologies Corp., Japan) scanning transmission electron microscope (STEM) that includes an automatic aberration correction function, and a large-solid-angle energy-dispersive X-ray spectroscopy detector that enables high-resolution and sensitive analysis. For observation with atomic resolution, using spherical-aberration-corrected STEM, in order that satisfactory performance of the device can be achieved readily, and within a short time, irrespective of the operator's skill level, a spherical-aberration-correction device with an automatic aberration-correction function was developed. This automatic aberration-correction function carries out the entire correction-related process (aberration measurement, selection and correction) automatically, with automatic selection of the aberrations that require correction, and automatic measurement of the appropriate corrections.
