python code for generating Filter Bank using for image retrieval. Contents including:
- Derive 2D Gaussion filter and Laplacian of Gaussion (LoG) (in report.pdf)
- Generate a filter bank of 48 image filters, each with 32 & times 32, including 4 Gaussion filters, 8 LoG filters, 18 x-directional first derivation of Gaussian filters and 18 x-directional second derivation of Gaussian filters
- Retrieve top5 images given a image query using filter bank and deep features
