Title: Parallel Image Processing Techniques, Benefits and Limitations
Abstract: The aim of digital image processing is to improve the quality of image and subsequently to perform features extraction and classification. It is effectively used in computer vision, medical imaging, meteorology, astronomy, remote sensing and other related field. The main problem is that it is generally time consuming process; Parallel Computing provides an efficient and convenient way to address this issue. Main purpose of this review is to provide the comparative study of the existing contributions of implementing parallel image processing applications with their benefits and limitations. Another important aspect of this study is to provide the brief introduction of parallel computing and currently available parallel architecture, tools and techniques used for implementing parallel image processing. The aim is to discuss the problems encountered to implement parallel computing in various image processing applications. In this research we also tried to describe the role of parallel image processing in the field of medical imaging.
