Frontal contour irregularities, sensory deficit of the forehead and loss of frontalis muscle function may occur following elevation and use of the galeal-frontalis flap. These three problems were evaluated retrospectively using a questionnaire and clinical examination in 48 cases. Frontal contour deformities were seen in 9 cases. Hypoesthesia of the(More)
Biometric technique has been implemented instead of conventional identification methods such as password in computer, automatic teller machine (ATM), and entrance and exit management system. We propose a personal identification (PI) system using color retinal fundus images which are unique to each individual. The proposed procedure for identification is(More)
Mirror image production is an extremely, useful tool for the craniofacial surgeon to visualize, in detail, asymmetry or defects, using data and display from three-dimensional CT scanning. The technique for obtaining the mirror image, its limitations, advantages and disadvantages are discussed and clinical cases are presented to demonstrate the usefulness(More)
As long as craniofacial 3-D imaging has been around, mirror imaging has been applied to copy the unaffected side onto the affected one [2, 4]. However, so far, mirror imaging has been a 2-D procedure, since the mirror operation was always carried out in the scan plane and for each scan separately. Fukuta et al. have now brought mirror imaging to the level(More)
Retinal vessel segmentation and delineation of morphological attributes of retinal blood vessels are utilized for diagnosis, screening and evaluation of various ophthalmologic diseases. In this paper, local entropy-based thresholding and modified Gaussian-based matched filter segmentation techniques have been performed on the bit plane sliced images to(More)
