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)
In this paper, a new dichotomization technique is proposed for multilevel thresholding. The proposed method is based on selection of the consistent peak location of the correlation function as threshold value over the interested histogram region. Different dichotomization processes are also adapted to the multilevel thresholding proposed by Yen et al.,(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)
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)
A case of immediate replantation of an avulsed scalp by microvascular anastomosis is presented. Microvascular replantation of the scalp seems to offer significant social and psychological advantages over secondary reconstructive procedures. The significance of the case presented is the regaining of the motor neural function of the facial nerve after 38(More)
