Digital Image Processing Book By Sanjay Sharma Pdf 13
The international conference on Advances in Computing and Information technology (ACITY 2012) provides an excellent international forum for both academics and professionals for sharing knowledge and results in theory, methodology and applications of Computer Science and Information Technology. The Second International Conference on Advances in Computing and Information technology (ACITY 2012), held in Chennai, India, during July 13-15, 2012, covered a number of topics in all major fields of Computer Science and Information Technology including: networking and communications, network security and applications, web and internet computing, ubiquitous computing, algorithms, bioinformatics, digital image processing and pattern recognition, artificial intelligence, soft computing and applications. Upon a strength review process, a number of high-quality, presenting not only innovative ideas but also a founded evaluation and a strong argumentation of the same, were selected and collected in the present proceedings, that is composed of three different volumes.

Beyond the machine itself, solid image processing is a key component of a diagnostic radiography program. While procurement of consumables for image processing is less of a logistical bottleneck than is the maintenance of the machine itself, analogue processing remains less desirable owing to challenges in storing the films, disposing of waste, and performing distant quality assurance on the images. Several groups have been developing digital retrofits of the WHIS-RAD. The up-front costs of digital technologies are significant, but the long-term benefits are substantial. Except in cases where excellent maintenance and servicing can be assured, however, we recommend having analogue as a back-up. In Nyaya Health's case, we chose analogue to start out of concerns about the costs and reliability of the digital system, though our long-term vision is to go digital (see case study below and table 3).
Subsequently, in 2010, Nyaya Health initiated an X-Ray program with a WHIS-RAD machine from the Spanish company Sedecal (Figure 2). Prior to deployment, our team discussed and investigated options for manufacturers and models extensively, particularly whether to purchase from an in-country (Nepal) or international company. We consulted with numerous experts throughout the world, and in fact our frustration with the current state of knowledge about the scale-up of x-ray services was the primary motivation for this piece. Ultimately we selected the WHIS-RAD system for the reasons we have discussed here. Implementing the x-ray program proved to be significantly more challenging than ultrasound services. Our first challenge was delivering equipment that weighed over 750 kg to an extremely remote region with limited road access. This was further complicated by the need to have a technician onsite to install it; this required a team to travel from Dehli (India) over 2 days away. Onsite challenges included effective training of a local staff member and developing reliable electricity to charge and operate the WHIS-RAD system. We worked with a regional hospital to train a mid-level provider (4 weeks) and have agreed to a 2 year bonding period to ensure the staff member is not drawn to an urban area where work is available and living conditions are far better. The second major challenge onsite was the electricity situation. Even though the WHIS-RAD has a battery source, it requires a 110 or 220 V supply, and the main electricity grid where Nyaya works was only supplying a degraded 170 V signal; this problem was fixed with the addition of a relatively inexpensive voltage stabilizer yet delayed implementation by several months. Presently we are deploying analogue film processing, though we hope to scale to digital in the future. We have documented our work on our wiki  and blog . In table 3, we provide the approximate costs of our x-ray deployment, which we used in planning services.
