摘要

One common technology for underground object detection is Ground Penetrating Radar. For landmine detection, it is vital to have a fast and accurate method. It becomes more difficult when it comes to online detection. A fast and low power consuming algorithm needs to be developed for better CPU performances. This paper uses synthetic data from GprMax program and proposes a 3-step method to locate and discriminate underground objects: 1) Pre-processing using n-rows average 2) Image scaling and 3) converting Region of Interest to a feature vector. Proposed method has been tested using 7 methods; 2 classification algorithms; and 3 different image scales. The proposed method has increased Overall Performance from 80.4% to 90.3% for K-Nearest Neighbors (KNN) with K = 5 where Histograms of Oriented Gradients had 91.8%. Although, detection performance for proposed method when KNN is used is slightly lower compared to HOG, proposed method has a good potential with its runtime performance and small representation capacity.
