Nonparametric statistical methods for image segmentation and shape analysis
Image segmentation, the process of decomposing an image into meaningful regions, is a fundamental problem in image processing and computer vision. Recently, image segmentation techniques based on active contour models with level set implementation have received considerable attention. The objective of this thesis is in the development of advanced active contour-based image segmentation methods ...
متن کاملTypological Description of Written Formative Feedback on Student Writing in an EFL Context
This study is a typological description of written formative feedback in an EFL context in Iran. Twenty M.A. students of TEFL participated in the study. They were required to summarize a scholarly article in each session on which the instructor would provide written corrective feedback (CF). Written formative comments were extracted, coded, and categorized into various types, such as asking for...
متن کاملModeling the Impact of News on volatility The Case of Iran
In this paper various ARCH models and relevant news impact curves including a partially nonparametric (PNP) one are compared and estimated with daily Iran stock return data. Diagnostic tests imply the asymmetry of the volatility response to news. The EGARCH model, which passes all the tests and appears relatively matching with the asymmetry in the data, seems to be the most adequate characteriz...
متن کاملObject Segmentation Based on a Nonparametric Snake with Motion Prediction in Video
Object segmentation in video sequence is a basic and important task in video applications such as surveillance systems and video coding. Nonparametric snake algorithms for object segmentation have been proposed to overcome the drawback of conventional snake algorithms: the dependency on several parameters. In this chapter, a new object segmentation algorithm for video, based on a nonparametric ...
