Over the past decade digital images has become a very popular way to communicate, store and process information. With the rapid advancement and easy availability of technology, there is a flood of devices that are able to capture, store and create digital images. Over the past years image processing techniques have been developed that makes it really easy to tamper images. From journalism to so...

The field of Signal Processing has witnessed the strong emergence of a new technique, the Blind Signal Processing (BSP) which is based on sound theoretical foundation. An offshoot of the BSP is known as Blind Source Separation (BSS). This digital signal processing techniques have a wide and varied potential applications. The term blind is indicative of the fact that both the source signal and t...

This paper reviews several studies of image de-noising on digital processing and applications. Noisy images contain different noise that exist either due to environment or electronic interferences. Ergo, is crucial eliminate the disturb data collecting process. The impact can result for accurate precise collected from image. Additionally, process required steps help enhance knowledge its applic...

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...

BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...

The quality of real-world photographs can often be considerably improved by digital image processing .In this article we describe our approach, integrating imaging and vision, for content-specific image enhancement. According to our approach, the overall quality of digital photographs is improved by a modular, image enhancement procedure driven by the image content. Single processing modules ca...

background and aims. the aim of the present study was to compare the effect of application of an image processing mode of a colorizer on the efficacy of the detection of interproximal carious lesions viewed in direct digital radiography. materials and methods. a total of 102 proximal surfaces of extracted human premolars on direct digital images were evaluated by three observers with and withou...
