Abstract: A method for auto-labeling images by using a class-agnostic refinement module is provided. The method includes steps of: (a) an auto-labeling device inputting the images into a coverage controlling module, to thereby allow the coverage controlling module to label objects on the images and thus to output first labeling data including first object region data and first class data; (b) the auto-labeling device inputting the images and the first object region data into the class-agnostic refinement module, to thereby allow the class-agnostic refinement module to label the objects on the images and thus to generate second object region data, and allowing the class-agnostic refinement module to align the first object region data and the second object region data to thereby output refined object region data; and (c) the auto-labeling device generating second labeling data including the first class data and the refined object region data.

Abstract: A method for auto-labeling images by using a class-agnostic refinement module is provided. The method includes steps of: (a) an auto-labeling device inputting the images into a coverage controlling module, to thereby allow the coverage controlling module to detect objects on the images and thus to output first object detection data including first bounding box data and first class data; (b) the auto-labeling device inputting the images and the first bounding box data into the class-agnostic refinement module, to thereby allow the class-agnostic refinement module to detect the objects on the images and thus to generate second bounding box data, and allowing the class-agnostic refinement module to align the first bounding box data and the second bounding box data to thereby output refined bounding box data; and (c) the auto-labeling device generating second object detection data including the first class data and the refined bounding box data.

Abstract: The present invention relates to a composition comprising chlorella extract for preventing or treating liver diseases. The composition comprising the chlorella extract according to the present invention may be applied to medical supplies and health supplementary food and the like, and the chlorella extract of the present invention may be usefully used as a composition for preventing or treating liver diseases because it shows inhibitory effect on liver function injury in a liver function injured model.

Abstract: An apparatus comprising a case, an optical amplifier, and an optical transceiver is provided. The optical amplifier and the optical transceiver are included in the case. The case includes a top portion and a bottom portion. The top portion includes first to third sections arranged in a direction perpendicular to a direction extending from the top portion to the bottom portion. The first section has a larger area than the third section and the second section divides the first and third sections. The third section includes a first cavity including at least one portion of the optical amplifier. The optical amplifier is provided using at least one of an amplifying fiber, a pumping light source, an isolator, a wavelength-division multiplexer (WDM) coupler, a wavelength-variable optical filter, a monitoring-tap photo diode, and a driving control unit.
