Cropping of individual ECG signal images for each lead: (A) The original 12-lead ECG scan with patient identifiable information redacted; (B) Baseline detection is used to determine the vertical distance between leads; (C) Lead name detection are used to determine the horizontal distance between leads; (D) Cropping to obtain each lead’s ECG signal. The width of the crop is the distance from end point of the lead name to the starting point of the adjacent lead name, while the height of the crop is 1.4 times of the vertical distance with the detected baseline in the middle.
