Abstract: The present disclosure relates to a method and device for generating a lane polyline by using a neural network model. The method according to an embodiment of the present disclosure may include generating a bird's-eye-view feature based on a base image obtained from at least one sensor mounted on a vehicle, and training a neural network model by using the bird's-eye-view feature as input data for the neural network model and using a lane polyline for a certain road as output data. In the present disclosure, a lane polyline obtained from the above-described neural network model may be used for controlling the vehicle without performing a separate process on the lane polyline.

Abstract: The present disclosure relates to a method and apparatus for generating a lane polyline by using a neural network model. The method according to an embodiment may extract a multi-scale image feature by using a base image obtained from at least one sensor loaded in a vehicle. According to the method, the multi-scale image feature is input to a first neural network model as input data and a BEV feature may be obtained as output data from the first neural network model. Also, according to the method, the BEV feature may be input to a second neural network model as input data and a polyline image with respect to a certain road may be obtained as output data from the second neural network model. In the present disclosure, a lane polyline obtained from the neural network may be utilized in vehicle control without going through an additional treatment process.

Abstract: The present invention relates to a food composition for enhancing immune function, which includes a fermented noni polysaccharide extract, and a method of preparing the same. The present invention may provide a polysaccharide extract prepared from a fermented noni extract. The present invention may provide a fermented noni polysaccharide extract, in which when the polysaccharide extract aqueous solution is provided at a concentration of 200 ?g/mL to RAW264.7 macrophages, an NO production value is 200% to 500% relative to RAW264.7 macrophages to which the polysaccharide extract solution is not provided.
