摘要: 為消除基本寬線檢測算子中的冗余計算量,提高算法的運算速度,該文提出一種寬線算子的快速實現(xiàn)方法隨機移動寬線算子。基本寬線算子采取逐像素移動模板的方式檢測圖像中的寬線特征,與之不同,隨機移動寬線算子在檢測時,隨機地在圖像中放置檢測模板,并根據(jù)當前像素類型采用啟發(fā)式的準則確定模板移動的策略,從而加快了模板移動速度,較好地消除了基本寬線檢測算法中的冗余運算;在此基礎上,提出了兩種提前結束條件,可根據(jù)檢測情況提前結束循環(huán),進一步節(jié)省了運算量。利用測試圖像對快速算子進行了實驗分析,結果表明,隨機移動寬線算子在取得相當檢測性能的同時,提高了基本寬線算子的運算速度。Abstract: To eliminate computation redundancy and improve speed of the basic wide line detector, a fast implementation, named randomized moving wide line detector, is proposed. Instead of moving the mask pixel by pixel to detect wide lines as did in the basic implementation, the randomized moving wide line detector places the mask in the image randomly, and then determines the mask moving strategy heuristically according to the current pixel. In this way, the mask moving is accelerated, leading to obvious decrease of computational redundancy in the basic detector. Furthermore, two early termination conditions are proposed to break out of the detecting loop based on the detection situation of wide lines. Testing images are adopted for performance evaluation of the randomized moving wide line detector. Experimental results demonstrate that the proposed detector accelerates the basic wide line detector significantly while keeping its detection performance unaffected.
