IMPORTANT NOTE: There was a serious error in the methodology used to compute the results on the INRIA dataset that are in this paper. Incorrectly cropped positive images were used, which led to boundary artifacts being used for classification.
We are extremely sorry about this mistake, and sincerely apologize for this error. The correct DET curve for the INRIA dataset appears below. The shapelet method does not outperform the HOG method of Dalal and Triggs.
