Abstract: The present disclosure relates to a method of generating high-purity hydrogen from waste plastic without producing carbon dioxide. In the method of generating hydrogen according to the embodiments of the present disclosure, reactants include hydroxide, and thus, the amount and purity of the generated hydrogen increases, a reaction temperature suitable for reaching an appropriate hydrogen production rate is lowered, and the amount of generated carbon dioxide is significantly decreased.

Abstract: An image acquisition apparatus includes: a multispectral image sensor configured to acquire images in at least four channels based on a second wavelength band of about 10 nm to about 1,000 nm; and a processor configured to estimate illumination information of the images by inputting the images of at least four channels to a deep learning network trained in advance, and convert colors of the acquired images using the estimated illumination information.
