摘要

This invention relates to a lighting method for illuminating an environment (A) by means of a plurality of light sources (2_ij), with i=1, . . . , N, where N is a positive integer and j=1, . . . , M, where M is a positive integer, wherein the method is comprised of the following steps: A. acquisition (110) of a video signal v(t), in which the image of each frame (3) is divided into a plurality of boxes (3ij); B. subdivision (120) of the video signal v(t) into a plurality of video signal boxes v_ij(t), each associated with the image portion of each frame (3) displayed on a respective box (3ij); C. frequency processing (130) of the frame video signals v_ij(t), for obtaining the spectra of the respective luminance custom-character

(f) and chrominance signals custom-character

(f) associated with each video signal box v_ij(t); D. extraction of the dominant frequency band (140) of the luminance signal spectrum custom-character

(f) associated with each box video signal v_ij(t); E. extraction of the dominant frequency band (150) of the chrominance signal spectrum custom-character

(f) associated with each box video signal v_ij(t); F. sum of the processed spectra of luminance and chrominance signals; and G. obtaining the time driving signal p_ij^Ctrl(t) of each of the light sources (2ij).;this invention also relates to a computer program, a storage medium and lighting system (IS).

9. 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.
