With the continuous development of computer science and technology, the field of Image processing is considered as a very active area of research. Digital Image Processing refers to processing of digital images by means of digital computer. The aim is to produce digital images with better contrast and hidden details. For this purpose, Image Enhancement techniques that process an input image so ...

The use of visual elements of an existing image while creating new ones is a commonly observed phenomenon in digital artworks. The practice, which is referred to as image reuse, is not an easy one to detect even with the human eye, less so using computational methods. In this paper, we study the automatic image reuse detection in digital artworks as an image retrieval problem. First, we introdu...

A digital image is a numeric representation of a two-dimensional image. Depending on whether the image resolution is fixed, it may be of vector or raster type. Without qualifications, the term "digital image" usually refers to raster images also called bitmap images. When we see a picture on our monitor or use our digital camera (or scanner), the image we are viewing or dealing with is not cont...

In the age of information and internet technology, images and videos having superior usage in various applications either for information sharing or authentication. The task of image manipulation has been simplified by the advances in digital imaging techniques. Nowadays many image editing tools can alter the features of an image, which is impossible to notice by naked eyes. Therefore the Relia...

Introduction: Various intraoral digital radiographic systems are available as an alternative to film-based radiography. Recent rapid progress in the field of digital radiography offers the possibility of image processing and manipulation. Pseudocolor filter is one of the tools of digital systems. The aim of this study was to compare diagnostic accuracy of proximal caries in black and white a...

objectives: in restorative dentistry, it is essential to estimate the amount of remnant tooth structure after caries removal to make the best treatment plan. the present study was aimed to determine whether there is a correlation between the real thickness of remnant dentin under carious lesion and the radiographical measurement from photostimulable phosphor plates (psps). methods: a whole numb...

introduction: the aim of this study was to compare digital and conventional radiography in determining the working length of dilacerated canals.methods: thirty nine human extracted single-rooted teeth with root curvature more than 35 degrees were included in this study. after access preparation, a file was inserted into the canal and advanced until the file tip was visualized at the foramen. wi...

Background: Distribution of radiographic images in the outpatient setting on compact discs-recordable (CD-R) iscommonplace. Opening, manipulating and interpreting these can be challenging. This study evaluated the availabilityand ease of use of CD-R to evaluate digital images in an outpatient orthopedic setting.Methods: 118 CD-R containing diagnostic studies were evaluated by ...
