摘要

A Drapemeter has been developed for the measurement of drape values by image processing. The results obtained are not significantly different from those obtained by the conventional method. The drape coefficient measured by pixel counting is closer to that of the conventional method, but the variation is higher than obtained by boundary approximation and Fourier Series. It does not require as much time and skill. It was found that, on repeated measurements, the variation was less than that of the conventional manual method. With the image analysis system, new measures of drape such as the drape distance ratio, number of nodes, fold depth index and amplitude to radius ratio, were defined. Repeated measurement has shown that drape shape is not constant, which causes the fabric to have different drape values. This instability of fabric drape makes it necessary to measure the drape values many times to allow drape values to be used as an objective index for drapeability. It is not easy to measure drape values many times with the conventional method, but the image analysis system makes it quite easy to take multiple measurements.

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.
