Abstract: The present application relates to a method for synthesizing image and an image synthesizing apparatus using the same. The image synthesizing method of the present application and the image synthesizing apparatus using the same can reduce the time required for learning by reducing the distortion phenomenon of the algorithm and reducing the amount of calculation required for image synthesis. In addition, the image synthesizing method of the present application and the image synthesizing apparatus using the same can be utilized in various fields such as national defense, IT, and entertainment based on characteristics such as excellent performance and learning time reduction of deep learning algorithms, and can be utilized in psychological warfare or induction of command system confusion.

Abstract: A polarizer plate includes a polarizer that includes polyvinyl alcohol and a dichroic material, the polarizer having a degree of orientation of 15 or more as represented by Equation 1: Degree of orientation=RD/RPVA×100, where RPVA represents a phase difference of the polyvinyl alcohol and RD represents a phase difference of the dichroic material.

Abstract: Poly(vinyl pivalate) exhibiting a high syndiotacticity and a high molecular weight is prepared through suspension polymerization of vinyl pivalate at low temperatures. Furthermore, poly(vinyl pivalate) microspheres with a high syndiotacticity is prepared for use as a precursor for PVA with a high molecular weight and a high syndiotacticity through suspension polymerization of vinyl pivalate at 20 to 70° C. with the use of azobisdimethylvaleronitrile as an initiator. In addition, poly(vinyl pivalate) is separated using a dispersing agent and a precipitating agent to thereby prepare poly(vinyl pivalate) microspheres with various sizes and a uniform size distribution. The poly(vinyl pivalate) microspheres are suspended in an aqueous alkali soloution such that only the surface thereof is saponified to PVA. In this way, embolic particles with a spherical shape are obtained to be useable as an embolic material for embolotherapy.
