Abstract: The present disclosure relates to a method and apparatus for representing dynamic neural radiance fields from unsynchronized videos. A method of acquiring a video at an arbitrary viewpoint based on a dynamic neural radiance fields model according to an embodiment of the present disclosure may comprise: inputting one or more videos acquired from one or more views for one scene into the dynamic neural radiance fields model; inputting a time embedding for the one or more videos into the dynamic neural radiance fields model; and rendering the video at the arbitrary viewpoint based on color information and density information output by the dynamic neural radiance fields model. Herein, time synchronization related to the time embedding may be performed by applying an individual time offset learned for each view, for the one or more views.

Abstract: An apparatus and method for testing a computer system by utilizing a Field Programmable Gate Array (FPGA) and programmable memory modules is provided. The apparatus includes a controller, a plurality of programmable memory modules, and an FPGA. Each programmable memory module stores configuration data of peripheral devices of the computer system in corresponding versions, respectively, which are differentiated according to functions of the computer system. Each memory module stores configuration data about a PCI host controller, a memory controller, a PLL, an interrupt controller, an arbiter, a UART, or a timer. The FPGA is programmed according to data stored in one memory module selected from among the programmable memory modules. Therefore, in the apparatus, the FPGA does not contain a bus bridge circuit, so that the FPGA has an increased programmable area and can be easily connected even with peripheral devices requiring many input and output ports.
