中文说明: 近年来有关视觉皮层细胞的数学建模研究 [Kulikowski/Marcelja/主教: 1982年] 建议调谐带通滤波器银行结构。 这些筛选器发现有高斯传递函数频率域。因此,考虑此传递函数的逆傅里叶变换咱们筛选器相似的 Gabor 滤波器的特性。Gabor 滤波器基本上是高斯 (与方差 sx和 sy 沿 x 轴和 y 轴分别) 通过复正弦信号调制 (与中心频率 u 和 V沿 x 轴和 y 轴分别)。 Gabor 滤波器主要用于形状检测和特征 extractin 图像处理中。 <
English Description:
Recent studies on Mathematical modeling of visual cortical cells [Kulikowski/Marcelja/Bishop:1982] suggest a tuned band pass filter bank structure. These filters are found to have Gaussian transfer functions in the frequency domain. Thus, taking the Inverse Fourier Transform of this transfer function we get a filter characteristics closely resembling to the Gabor filters. The Gabor filter is basically a Gaussian (with variances sx and sy along x and y-axes respectively) modulated by a complex sinusoid (with centre frequencies U and V along x and y-axes respectivel
