Laboratory IMPEG7 implementation exercises

Ing. Marco Bertini

Exercise objectives

• Perform experiments with a sample CBIR system based on MPEG-7 features

• Experiment with weighted retrieval

• Experiment with approximate retrieval

Working tools

• Use Java CBIR module based on LIRE open source library – use version 0.9.4

• Use UCID V2 dataset for testing.

• Source code available for inspection

• Word and Latex template for 4-page resume of the experiments (to be done per group)

Task

• Using the CBIR module perform image retrieval by applying:– CLD– SCD– EHDand their (weighted) combinations.

• Check the most appropriate feature combinations to optimize performance

• Test on UCID dataset and evaluate MAP P@10 using ground truth data.
