An application of topological median filters on detection and clustering of microcalcifications in digital mammograms
Existence of microcalcification clusters on mammograms is one of the earliest signs of breast cancers. In this study, a method that is based on topological median filters is proposed for the automated detection of ... -
DGridSim: a multi-model discrete-event simulator for real-time data grid systems
Doğan, Atakan; Atanak, Mustafa Mujdat; Tandoğan, Safai; Altuğ, Reha Oğuz; Şenel, Hakan Güray (SAGE Publications LTD, 2014)Data grid systems are utilized to share, manage, and process large data sets. On the other hand, an increasing number of applications with real-time constraints arise in several disciplines of science and engineering. The ... -
Gradient Estimation Using Wide Support Operators
Şenel, Hakan Güray (IEEE-Inst Electrical Electronics Engineers Inc, 2009)One of the fastest methods of localizing edges in images is based on small gradient kernels, such as Sobel, Prewitt, and Roberts. Although small gradient kernels provide a fast way of computing the gradients, they have ... -
Gray Level Topological Angle Detection of High Curvature Points
Cihan, İbrahim Kıvanç; Şenel, Hakan Güray (IEEE, 2010)A new method of angle detection based on the topological median filter is proposed. Topological opening operator is used to detect corners and Topological closing operator is used to calculate the corner angles on gray ... -
Gray level topological corner detection
Cihan, İbrahim Kıvanç; Şenel, Hakan Güray (IEEE, 2007)A new corner detection algorithm based on the topological median filter is proposed. Topological quasi dilation and erosion operators with circular structuring element are used to detect the corners on gray level images. -
Image Gradient Estimation with Wide Support Kernels
Şenel, Hakan Güray (IEEE, 2008)Gradient estimation using small support kernels is often used in edge detection algorithms. Small kernels such as Sobel and Roberts are often used in order to obtain gradient estimation in a short time. However, the limited ... -
Topological gradient operators for edge detection
Şenel, Hakan Güray (IEEE, 2007)Edge detection in image processing is the task of locating pixel value variations in images. First methods were directional derivative based linear filters. One of the most important problems of these methods that are based ... -
Topological median filters
Şenel, Hakan Güray; Peters, RA; Dawant, B (IEEE-Inst Electrical Electronics Engineers Inc, 2002)This paper describes the definition and testing of a new type of median filter for images. The topological median filter implements some existing ideas and some new ideas on fuzzy connectedness to improve, over a conventional ... -
