Abstract: There are provided a method, apparatus, system, and computer-readable recording medium for image compression. An encoding apparatus performs domain transformation and quantization on feature map information and image information. The encoding apparatus rearranges the result of domain transformation and quantization so as to have a form advantageous to the encoding procedure and encodes the result of rearrangement, thereby generating a bitstream. A decoding apparatus receives the bitstream, decodes the received bitstream, and performs inverse transformation, dequantization, and inverse rearrangement using information transmitted through the bitstream. The result of inverse transformation, dequantization, and inverse rearrangement is used for the machine-learning task of a neural network.

Abstract: A method for producing microparticles produces microparticles of uniform size and narrow density range. Therefore, the method for producing microparticles exhibits a higher production yield compared to a conventional method for producing microparticles. The microparticles produced from the method have a density lower than that of water and their range is very narrow, and thus, when used as a microcarrier, they enable cell culture with high efficiency without problems floating up onto the surface of the culture medium during the cell culture process. Moreover, the microparticles are easily separated and recovered after the culture process.
