摘要

The concepts presented in the paper were developed to establish a uniform method of evaluating the recognition of optical character readers used to process the information on forms which receive information as a bit stream directly or indirectly from scanners. Many large data entry systems are being designed to collect data from specified areas of forms, some of which may be multipart and completed with machine-printed or hand-printed characters. As the technology continues to advance, the number of commercially available products is increasing. Multiple products are emerging, all of which are designed to solve optical character recognition (OCR) applications. Improved recognition algorithms have enabled the accuracy of these products to steadily increase, but each product is based on a different, often proprietary set of algorithms. This presents potential users of OCR technology with many different choices and options and leads to a series of significant questions: How does a person determine when the technology has matured enough to make it economically advantageous to deploy; How does a potential user determine which product is best for his or her specific needs; How can a system developer, who has the ability to choose from a large variety of diverse algorithmic approaches, intelligently choose and then track progress when developing OCR systems. The answer to these questions lies in objective system performance measurement. This is the motivation behind the paper.

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.
