为了降低浮点运算导致的舍入误差,提高初始倾斜角度的检测精度,在基于能量频谱图检测方法的基础上引入了一个空域的基于平行线覆盖的快速收敛方法.新方法结合了频域和空域的信息,不仅提高了检测精度,同时保持了基于能量频谱图检测方法对污损噪声图像的鲁棒性.
A high accuracy skew detection method based on periodic texture is presented by introducing an effective converging method. Combining the information of frequency domain and spatial domain,the proposed method not only remarkably improves the accuracy of detected skew angle but also continues the robustness of original method for noised and contaminated images.
