An adaptive thresholding approach for automatic optic disk segmentation
Optic disk segmentation is a prerequisite step in automatic retinal screening systems. In this paper, we propose an algorithm for optic disk segmentation based on a local adaptive thresholding method. Location of the optic disk is validated by intensity and average vessel width of retinal images. Then an adaptive thresholding is applied on the temporal and nasal part of the optic disc separatel...
متن کاملHybrid Approach for Voltage Sag Mitigation in Distribution System
Voltage sag is one of the severe forms of power quality problems in distribution network. It should be mitigated as soon as possible for preventing the load from getting damaged. In the paper, a hybrid approach for voltage sag mitigation in distribution system is proposed. Mitigation is performed by optimally installing DG units in the network. In the hybrid approach, we use two well known Arti...
متن کاملFractional adaptive control for an automatic voltage regulator.
This paper presents the application of a direct Fractional Order Model Reference Adaptive Controller (FOMRAC) to an Automatic Voltage Regulator (AVR). A direct FOMRAC is a direct Model Reference Adaptive Control (MRAC), whose controller parameters are adjusted using fractional order differential equations. Four realizations of the FOMRAC were designed in this work, each one considering differen...
متن کاملAn Approach for Automatic Matching of Descriptive Addresses
Address matching (also called geocoding) is an applied spatial analysis which is frequently used in everyday life. Almost all desktop and web-based GIS environments are equipped with a module to match the addresses expressed in pre-defined standard formats on the map. It is an essential prerequisite for many of the functionalities provided by location-based services (e.g. car navigation). Sever...
متن کاملAn Improved Pixon-Based Approach for Image Segmentation
An improved pixon-based method is proposed in this paper for image segmentation. In thisapproach, a wavelet thresholding technique is initially applied on the image to reduce noise and toslightly smooth the image. This technique causes an image not to be oversegmented when the pixonbasedmethod is used. Indeed, the wavelet thresholding, as a pre-processing step, eliminates theunnecessary details...
