Abstract: Provided are an automatic driving system and method using a driving experience database for safe driving by traffic situations. The automatic driving method includes receiving driving information about surrounding vehicles located near a first vehicle, receiving information about the event and driving information about the first vehicle when an event which is set for the first vehicle occurs, storing the driving information about the surrounding vehicles and the driving information about the first vehicle in association with the information about the event to build a database, and performing learning on a driving behavior of the first vehicle, based on the occurrence of the event.

Abstract: Provided are an apparatus and method for extracting a salient line for an information sign. The apparatus includes an image input portion configured to receive an image including information indication lines to be detected, a signal calculator configured to generate a symmetric function signal consistent with a thickness and a direction of an information indication line having a preset thickness in the received image and perform a convolution of the information indication line and the generated symmetric function signal, a highest value enhancement portion configured to enhance highest values in results of the convolution using a signal quality improvement filter, and a local highest value extractor configured to find local highest values among the enhanced highest values and extract a line connecting the local highest values as a salient line connecting center points in the information indication line.
