[Special Effects] 1D gabor Filter DL : 0: 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 respectively).

[Special Effects] gabor DL : 0: Gabor小波变换代码用于局部特征提取使用，又相当好的效果-Gabor texture descriptor have gained much attention for different aspects of computer vision and pattern recognition. Recently, on the rayleigh nature of Gabor filter outputs Rayleigh model Gabor texture descriptor is proposed. In this paper, we investigate the performance of these two Gabor texture descriptor in texture classification. We built a texture classification system based on BPNN, and use the corresponding feature vector from traditional Gabor texture descriptor or Rayleigh model one as input of BPNN. We use three datasets from the Brodatz album database. For all the three datasets, the original texture images are subdivided into non-overlapping samples of size 32 × 32. 50 of the total samples are used for training and the rest are used for testing. We compare the system training time and recognition accuracy between two Gabor texture descriptor. The experimental results show that, it takes more time when using Rayleigh model Gabor texture descriptor than tr
