Fingerprint compression is essential to store more number of fingerprints in the digital storage media as well as transfer from one place to another using network faster. This paper deals with various compression techniques such as JPEG, wavelet, SPHIT, modified SPHIT, EZW and edge detection methods for fingerprint image.

High Dynamic Range Image Compression of Color Filter Array Data for the Digital Camera Pipeline Dohyoung Lee Master of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2011 Typical consumer digital cameras capture the scene by generating a mosaic-like grayscale image, known as a color filter array (CFA) image. One obvious challenge in digital phot...

Medical images have become the recent key investigation tools for medical diagnosis and treatment planning. Due to the advent of digital imaging the need of data storage and retrieval of medical images increased rapidly. Some difficulties in retrieving the medical images are: medical images have only intensity images that carry less information, more noise and records of medical images are larg...

Recent advances in digital imaging is impacting the practice of pathology. One of the key enabling technologies that is leading the way towards this transformation is the use of whole slide imaging (WSI) which allows glass slides to be converted into large image files that can be shared, stored, and analyzed rapidly. Many applications around this novel technology have evolved in the last decade...

Computer technology these days is most focused on storage space and speed. Considerable advancements in this direction can be achieved through the usage of digital image compression techniques. In this paper we present a well studied singular value decomposition based JPEG image compression technique. Singular Value Decomposition is a way of factorizing matrices into a series of linear approxim...

This work addresses the question of determining the correctness of forensic file system analysis software. Current storage systems are built on theory that is robust but not invincible to faults, from software, hardware, or adversaries. Given a parsing of a storage system of unknown provenance, the lack of a sound and complete analytic theory means the parsing's correctness cannot be proven. Ho...

We have examined the radiological images used for illustration of research and case reports in this journal for the last twelve months. We have found that a number of illustrations patient’s images contained multiple patient identifiers including gender, age, date of birth and medical record number, which amount to an inadvertent breach of patient confidentiality. These are generally seen whe...

The increasing attractiveness and trust on digital photography has given rise to its use for visual communication. It requires storage of large quantities of data. Due to limited bandwidth and storage capacity, images must be compressed before storing and transmitting. Many techniques are available for compressing the images. But in some cases these techniques will reduce the quality and origin...

The advancement in image diagnostic methods has been great in recent years and image diagnosis has become indispensable for the diagnosis of renal and other cancers. However, the clinical images are fixed and recorded on film as analog images for storage and the expansion of storage space, the poor efficiency in arrangement and control and the inconvenience of transfer have become big problems....
