In the field with real robots, it is important to well perceive the location of ball, team robots and opponent robots through the vision system in real time. In this paper the architecture of global vision system of our small size robotic team and the process of object recognition is described. According to the study on color distribution in different color space and quantitative investigation, a method which uses H (Hue) thresholds as the major thresholds to feature exact and recognize object in real time is presented.展开更多

The change of accounting standards adopted by Turkey started to be implemented, and this created a number of qualitative and quantitative results. This study examines the impact of change of accounting standards on accounting quality. In order to determine how switching standard reflects accounting quality, first of all, the earnings management, timely loss recognition, and value relevance variables pertaining to accounting quality were listed and the findings were stated after subjecting the obtained data to statistical analyses. Accordingly, by the transition to International Financial Reporting Standards （IFRS）, the earnings management practices were observed to decrease as compared with the pre-IFRS period and the timely loss recognition and value-relevance values were observed to increase, which constitute the dimensions of accounting quality. It was also concluded that by the switch from domestic accounting standards to International Accounting Standards （IAS）, the quality of accounting in the country was improved and the market became more active than it was before.展开更多
