raw cane sugar is one of the most important product in the sugar industry and is the main raw material for the white sugar production. morphological and physical properties of this product might influence the final white sugar. for instance, the behavior during centrifugation, transport and storage is related to the characteristics of these crystals. the object of this study was to determine th...

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...

Transmission, manipulation and storage of images in digital format is rapidly becoming an everyday practice. Desktop publishing, digital libraries, image databases and the World Wide Web are only some of the application areas that are strongly related to digital imaging technology. The new digital, networked environment necessitates the development of robust and trustworthy encryption, authenti...

Digital Color Image required large amount of space to store and large bandwidth to transmit it. Due to limitations in bandwidth and in storage space, it is vital requirement to compresses digital color image. Color image compression is required with negligible loss in image quality for the effective use of further restored image. To meet this, numerous image compression techniques are developed...

INTRODUCTION Every imaging system starts with an image sensor. The signal from the sensor must be processed in the analog domain, converted to digital, and further processed in the digital domain. This allows the image to be analyzed, manipulated, and enhanced, prior to storage, display, transmission, and/or further processing. Imaging applications typically involve three chips—an image sensor,...

The rapid growth of digital imaging applications, including desktop publishing, multimedia, teleconferencing, and high visual definition has increased the need for effective and standardized image compression techniques. Digital Images play a very important role for describing the detailed information. The key obstacle for many applications is the vast amount of data required to represent a dig...
