Image quality enhancement in digital panoramic radiograph
One of the most common positioning errors in panoramic radiography is palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to the pati...
متن کاملContrast Enhancement Estimation for Digital Image Forensics
Inconsistency in contrast enhancement can be used to expose imagel forgeries. In this work, we describe a new method to estimate contrast enhancement from a single image. Our method takes advantage of the nature of contrast enhancement as a mapping between pixel values, and the distinct characteristics it introduces to the image pixel histogram. Our method recovers the original pixel histogram ...
متن کاملFuzzy Based Contrast Stretching for Medical Image Enhancement
Contrast Stretching is an important part in medical image processing applications. Contrast is the difference between two adjacent pixels. Fuzzy statistical values are analyzed and better results are produced in the spatial domain of the input image. The histogram mapping produces the resultant image with less impulsive noise and smooth nature. The probabilities of gray values are generated and...
متن کاملDeveloping a PC-based portal image contrast enhancement program
ABSTRACTBackground: Delivering the radiation dose to the target volume and minimizing the dose to normal tissues are the main objectives in radiotherapy. The aim of our study is to enhance the contrast of the portal image to increase the accuracy of delineation of the organs in the irradiation field. Methods: The software was written based on local enhancement of the pixel values in image ma...
متن کاملRevealing Image Forgery on Digital Images by applying Contrast Enhancement
Image manipulation is a malicious threat that is occurring nowadays. The trustworthiness of images is lost. Malicious users have many photo editing software's to manipulate images in many ways such as brightness changes, contrast manipulations and creating composite images. Here in this, it proposes two novel methods to detect contrast manipulations and composite images. First, it detects the m...
