With the advancements in the field of digital image processing during the last decade, digital image data hiding techniques such as watermarking, Steganography have gained wide popularity. Digital image watermarking techniques hide a small amount of data into a digital image which, later can be retrieved using some specific retrieval algorithms to prove the copyright of a piece of digital infor...

With interest we have read the article of Casparie et al. on the Dutch PALGA system [1]. The paper certainly makes clear what a unique system PALGA is and what role PALGA could play in biobanking. From our point of view, one important issue with regard to national storage is however not addressed, which is the incorporation of digital images. Besides the fact that including digital macroscopic ...

storage devices today, combined with the rapid expansion of broadband Internet connectivity, has given consumers more control over their digital photo collections than ever before. There’s virtually no limit to the amount of digital images we can keep and store on our PCs. As a result, the emerging challenge is searching through these digital image collections. With no information about the ima...

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...

Volume of the information on the World Wide Web has become very huge in which digital images occupy the largest chunk of such information due to availability of good-quality digital photographic tools in affordable prices. Goal of ongoing research in the field of Image Retrieval is not only the expansion of storage capacity but also the development of effective and efficient retrieval technique...

This article on digital radiography image processing and display is the second of two articles written as part of an intersociety effort to establish image quality standards for digital and computed radiography. The topic of the other paper is digital radiography image acquisition. The articles were developed collaboratively by the ACR, the American Association of Physicists in Medicine, and th...

Digital maps can be stored and distributed electronically using compressed raster image formats. We introduce a storage system for the map images that supports compact storage size, decompression of partial image, and smooth transitions between various scales. The main objective of the proposed storage system is to provide map images for real-time applications that use portable devices with low...

Usage of digital media has witnessed a tremendous growth during the last decades, as a result of their notable benefits in efficient storage, ease of manipulation and transmission. However these features make digital media vulnerable to copyright infringement, tampering and unauthorized distribution. In the last five years the protection of digital information has received significant attention...
