  • Publication number: 20230093734
    Abstract: According to implementations of the subject matter described herein, a solution for image rescaling is proposed. According to the solution, an input image of a first resolution is obtained. An output image of a second resolution and high-frequency information following a predetermined distribution are generated based on the input image by using a trained invertible neural network, where the first resolution exceeds the second resolution. Besides, a further input image of the second resolution is obtained. A further output image of the first resolution is generated based on the further input image and high-frequency information following the predetermined distribution by using an inverse network of the invertible neural network. This solution can downscale an original image into a visually-pleasing low-resolution image with the same semantics and also can reconstruct a high-resolution image of high quality from a low-resolution image.

  • Publication number: 20220335588
    Abstract: An image inspection apparatus includes a learned neural network storage storing a neural network that previously learns weighting factors between input, intermediate and output layers, and an inferer determining failure/no-failure of a workpiece and classify the workpiece to classes based on an image of the workpiece. The inferer performs first and second inferences. In the first inference, the inferer determines failure/no-failure of the workpiece based on failure/no-failure feature quantities that are obtained by providing the workpiece image to the neural network and a failure/no-failure determination boundary.

  • Patent number: 10052668
    Abstract: A process for treating waste from a pithead power plant and sequestrating carbon dioxide discharged therefrom is provided. A mixed material of solid waste from the power plant, cement and a mixing liquid is filled into a depleted coal mine and compacted. A hydrating liquid is then injected into the filler after compaction to cause hydration. After that, carbon dioxide discharged from the power plant is injected to mineralize the carbon dioxide, thereby achieving carbon dioxide sequestration and reinforcement of the depleted coal mine. The invention utilizes abundant basic oxides present in the solid waste, and the fact that calcium hydroxide and tobermorite present in the hydrated cement chemically react with the injected carbon dioxide to produce stable carbonates in solid, and thus simultaneously achieves carbon dioxide sequestration, treatment of solid waste, and reinforcement of a depleted coal mine.
