This is a time-frequency analysis program implementing Gabor transform, which demonstrates excellent frequency separation capabilities. The Gabor transform parameters include constants a and b, where a represents the grid interval length and b represents the grid frequency length. The expansion coefficients correspond to one-dimensional signal x(t), with h(t) as the mother function generating basis functions through shifting and modulation operations.

Image texture recognition based on Gabor transform with algorithmic enhancements. This study presents an improved Gabor transform algorithm for texture enhancement, converting spatial domain texture images to joint spatial-frequency domain and utilizing energy distribution as palmprint features. The implementation involves Gabor filtering of frequency energy distribution along principal directions in sub-blocks, feature vector matching, multi-directional spatial-frequency energy filtering synthesis for enhanced ridge information, and computational optimization for reduced processing load.
