摘要

The object of this study is to devise a simple technique to provide digital access to fragile paper-based colour maps and images that might otherwise be damaged by misuse and abusive handling. On the basis of certain physical attributes, five different map and image types are defined. Using low cost equipment and software, seventeen representative maps and images were digitized. The digital files were then compressed, indexed and re-formatted, and a selection of these images were used in a survey of undergraduate students testing the legibility and colour reproduction of the various combinations of digital attributes.; The study suggests that there is a positive relationship between increased scanning resolution and both increased legibility and better colour reproduction. Furthermore, the study concludes that, for certain image types, there is a negative relationship between bit depth and image sharpness. Finally, the study arrives at the determination that every image must be treated individually, and standards for digitization must be customized for every image type.

7. ABSTRACT Various body parts or organs can be analysed to identify the different diseases in the human body. Fingernail analysis is one of the ways to identify disease in the human body. Nails are the body part which are farthest from the heart and therefore receive oxygen at last. As a result the nails are the first who show the symptoms of a disease in the human body. Fingernails can be easily captured for diagnosis and there are no heavy equipment or no specific conditions required to use nail image for disease diagnosis, like in other tests and scanning processes. Human nails deliver beneficial information about complaints or any nutritive imbalances in the human body depending upon their shape, texture and colour. In human beings, numerous systemic and skin diseases can be easily analyzed through careful examination of nails of both the limbs. A lot of nail illnesses have been found to be primary signs of numerous underlying systemic illnesses. The colour, texture or shape changes in nails are signs of many diseases mainly affecting nails. Considering all these properties of nails a system is proposed that uses digital image processing (DIP) methods for identifying such changes in the human nail to get more precise results and predict numerous diseases effortlessly. With the emerging Internet of Things (IOT) concept the generated report is made available remotely, this will help users to reduce transportation efforts. As the system has to deal with large and private data, the security of data must be ensured. To keep the data confidential, the Blockchain concept which is one of the most emerging concepts in the field of data management is used. The paper contains the implementation of the digital image processing for feature extraction of nail images, usage of IOT (ThingSpeak cloud) for data storage and implementation of Blockchain to keep the system secured and theft free.
