摘要

The prognosis for cancer patients becomes much better if a tumor is diagnosed, localized and treated early, in a precancerous stage. The difficulty lies in the localization of cancerous tumors. Carcinoma in situ (CIS) refers to a tumor which is approximately 100 microns thick and one which has not penetrated through the epithelium wall or become invasive (2). A tumor of this size cannot be detected by existing techniques such as x-ray, computer tomography, magnetic resonance imaging, nuclear medicine or conventional endoscopy under white-light illumination. However, these tumors can be localized and destroyed by photodynamic diagnosis and therapy. This research shows that digital image processing and the technique of digital image ratioing contribute to photodynamic diagnosis and the early localization of cancer. A software package has been developed as a result of this research. The software package quantifies the usefulness of digital image processing for tumor localization and detectability. System parameters such as the endoscope distance and angle variations, tumor size and tumor concentration, sensitivity and specificity of the system have been tested and quantified.

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.
