We conduct an exhaustive survey of image thresholding methods, categorize them, express their formulas under a uniform notation, and finally carry their performance comparison. The thresholding methods are categorized according to the information they are exploiting, such as histogram shape, measurement space clustering, entropy, object attributes, spatial(More)
Here, we established a protocol for induction of somatic embryogenesis and plant regeneration from immature cotyledons of open-pollinated seeds of European chestnut (Castanea sativa Mill.) cultivars ‘Osmanoğlu’ and ‘Sarıaşlama’. Basal media, Murashige and Skoog medium (MS), Driver and Kuniyuki Walnut medium (DKW), and Woody Plant Medium (WPM) supplemented(More)
—In this work, we contribute to the real-time detection of buried objects, with special emphasis on explosive ones, using the ground penetrating radar (GPR). When the buried objects have explosive substance, the moment of detection becomes vital. Therefore, we start the detection process right after the very first GPR signals begin to return from the buried(More)
In this paper a novel multilevel thresholding method is proposed based on selecting the consistent peak of correlation function over the interested histogram region. The histogram is separated into two more regions up to the cost function is reached minimum. In the separation process of the histogram, a novel dichotomisation method is used. In general,(More)
Follicular unit extraction (FUE) is a recent and widely used surgical procedure for hair restoration (1,2). Complications are rarely reported in literature. Herein, we report the first case of recipient site ne-crosis. We used hyperbaric oxygen therapy (HBOT) as an adjunctive therapy in this patient in order to restrict necrosis area in length and depth and(More)
Image binarization is still a relevant research area due to its wide range of applications in the field of document analysis and recognition. Accuracy of binarization methods affected by many factors such as shadows non-uniform illumination, low contrast, large signal-dependent noise etc. This paper provides a comprehensive survey of major binarization(More)
