Abstract: There is provided a multi-view video coding artifact reduction method and system. According to an embodiment, the multi-view video coding artifact reduction method selects reference fames in neighbors of a current frame constituting a multi-view video, derives unidirectional flows and bilateral flows between the current frame and the reference frames, warps the reference frames based on the derived flows, generates intermediate frames by fusing the current frame, the reference frames, and the warped reference frames, and generates a final frame by fusing the current frame and the intermediate frames. Accordingly, image quality of the multi-view video can be more enhanced.

Abstract: There are provided an apparatus and a method for reconstructing a 3D human object in real time based on a monocular color image. A 3D human object reconstruction apparatus according to an embodiment extracts a pixel-aligned feature from a monocular image, extracts a ray-invariant feature from the pixel-aligned feature, generates encoded position information by encoding position information of a point, predicts a SD of a point from the ray-invariant feature and the encoded position information which are extracted, and reconstructs a 3D human object by using the predicted SD. Accordingly, the ray-invariant feature extracted from the pixel-aligned feature, and the encoded position information are used, so that an amount of computation for predicting SDs of points of a 3D space can be noticeably reduced and a speed can be remarkably enhanced.

Abstract: A control method for stabilizing excimer laser pulse energy includes: obtaining a measured energy value of the n-th pulse in a pulse sequence; calculating the difference between the measured energy value and the preset energy value; taking the z-th pulse of the sequence as a demarcation point, when n is a positive integer less than z, the discharge voltage value of the next pulse is calculated according to a first mathematical model, and when n is an integer greater than z?1, the discharge voltage value of the next pulse is calculated according to a second mathematical model; and the next pulse is generated according to the discharge voltage value. A control system based on the control method includes: a high-voltage discharge module, a laser cavity, a laser parameter measurement module, and an energy stability controller.
Abstract: Configuration information is sent from a configuration controller to a processor module in a System On Chip (SOC) and associated with firmware. In response to receiving the configuration information, context switching associated with an interrupt pin in the processor module is disabled. Hardware state information is sent from a hardware functional module in the SOC to the interrupt pin. In response to receiving the hardware state information, the processor module determines, based at least in part on the hardware state information and after completing any active firmware operations per the disabled context switching, a response. The response is received at a responding module and the responding module performs a process associated with the response.
Abstract: An avatar carrier generating system for metaverse and method thereof are disclosed. Before a living body enters a metaverse, a sensing element senses the living body to generate a physiological feature, and after a real-name identity message is received, the real-name identity message and the physiological feature are converted into metadata compliant with a non-fungible token standard; the non-fungible token, which is owned by the living body, is generated on the blockchain based on the metadata. When the living body enters the metaverse, an avatar carrier for entering the metaverse is generated based on the metadata of the non-fungible token, and when the avatar carrier receives an identification request, the avatar carrier is permitted to provide at least one of the physiological feature and the real-name identity message, so as to achieve the effect of improving identifiability and authentication of the avatar carrier of the metaverse.
Abstract: A continuous hologram recording method is provided. A holographic printer according to an embodiment of the present invention comprises: a light source that emits light; a modulator that modulates the light emitted from the light source, to generate a holographic fringe pattern in units of hogels; a stage having placed thereon a hologram recording medium on which a holographic fringe pattern generated by the modulator is to be recorded in units of hogels; a first driving unit that moves the position of the stage in a first axial direction by using a first-type motor; and a second driving unit that moves the position of the stage in a second axial direction by using a second-type motor different from the first type.

Abstract: A patch based depth mapping method and apparatus for high-efficiency encoding/decoding of a plenoptic video is proposed. The method may be performed in an electronic apparatus to classify a reference image and an additional image from a plenoptic video during encoding the plenoptic video and then generate an atlas including a patch using the additional image. The method may include mapping a depth value by applying minimum-maximum linear scaling in units of an input viewpoint image. The method may also include finding a minimum value and a maximum value of the depth value per the patch and remapping the depth value through minimum-maximum linear scaling.

Abstract: The present utility model discloses a buckle type earmuff, comprising two ear-wrapping covers with connecting buckle plates on their outer side walls and a wearing band mounted between the two connecting buckle plates. Embodiment 1: when worn by an adult, the distance on the elastic plate can be adjusted by pulling the two connecting buckle plates. After adjustment, the clamping block and buckle secure the two ear-wrapping covers to the connecting buckle plates, making it ready for use. Embodiment 2: when used by a kid, Adjust the size of the band ring formed by the elastic. After adjustment, both support housings are buckled onto the adjusted elastic band along with their respective main bodies of buckle plates. This allows the elastic to wrap around the forehead and back of the child's head.
