Abstract: Provided are an apparatus and method for correcting sensing of a surrounding obstacle on a curved road. The apparatus includes an acquisition unit configured to acquire curvature information of a curved road on which a vehicle is traveling using a steering angle value indicating a degree of rotation of a steering wheel of the vehicle, a sensing unit configured to sense another vehicle traveling behind the vehicle, and a correction unit configured to correct sensing information of the other vehicle sensed by the sensing unit using the curvature information acquired by the acquisition unit.

Abstract: Provided are an apparatus and method for detecting ventricular depolarization (QRS) of an electrocardiogram (ECG). The apparatus includes an input unit configured to receive an ECG signal, a memory configured to store a program for detecting R and ventricular depolarization using the ECG signal, and a processor configured to execute the program, wherein the processor detects a QRS interval and an R-peak using a first-order derivative filter and a max-filter.

Abstract: Provided is a method of detecting the R peak of an electrocardiogram (ECG) signal using an adaptive median filter. The method includes allowing an ECG signal (hereinafter, referred to as a first ECG signal) received from an ECG signal measuring apparatus having a predetermined sampling rate to pass through an adaptive median filter, calculating a difference value between the first ECG signal and a signal (hereinafter, referred to as a second ECG signal) passing through the adaptive median filter, extracting R peak candidate groups by applying a maximum filtering size and an adaptive threshold applicable in the adaptive median filter to the calculated difference value between the first and second ECG signals, and detecting an R peak candidate group having a maximum value among the R peak candidate groups as an R peak.
