In this paper, we propose the joint deconvolution and segmentation of materials images by incorporating blurring information in the EM/MPM segmentation algorithm. In the segmentation of microscope images of materials, exact boundary precision is very important. But it is difficult to get good results if the images have some degradation obtained in the(More)
The Markov Random Field (MRF) has been used extensively in Image Processing as a means of smoothing interfaces between differing regions in an image. The MRF applies a total boundary length `energy' penalty that is subsequently minimized by an inversion algorithm. The minimization of energy implies a force associated with boundaries, the sum of which must(More)
This paper describes a test-bed for verification and validation activities in KT-NeOSS (Korea Telecom New Operations Support System) development. In this paper, we show the test phases for performing verification and validation activities during the development and maintenance of KT-NeOSS. We describe the experiences and considerations in building the(More)
The failure behavior of the Smart Power IC using a 0.35 μm Bipolar-CMOS-DMOS was investigated, and the major ESD failure spots were found at the corner of the guard-ring structure and the high-voltage transistor, which is connected between the different power domains (Vdd-Vcc). The mechanism of these failures is investigated by the T-CAD simulation,(More)
This paper describes the design and implementation of a Graphical User Interface (GUI) for the layered network topology and the connections in an Asynchronous Transfer Mode (ATM) network managed by the ATM Network Management System (NMS). There are physical and logical networks in an ATM network. In addition, the ATM connections, which are ATM Permanent(More)
This paper describes the testing activities for the development of the KTOSS (Korea Telecom Operations Support System). In this paper, we show the test phases for performing the verification and validation activities for the development and maintenance of KT-OSS. They are based on the general software development lifecycle, with an operational test added to(More)
