You can use the program gift-extract-features that is built and installed when you install GIFT. It requires a 256x256 PPM image file as a parameter on the command line. If your image file is, for example, 001.gif, you would do: >convert -geometry 256x256 001.gif 001.ppm; gift-extract-features 001.ppm; rm 001.ppm This will create a file 001.fts in the same directory, that includes the extracted features. > What would be steps to follow for anybody who wants to use GIFT to indexing and features extraction only? The gift-add-collection.pl program extracts features and builds the index files for all the images in a directory. If you just want to extract features and index using those GIFT components, that is what you need to use, just as if you were going to use the gift query engine as well. You will need to dig in the source code to understand the format of the feature and index files. > Any idea where I can find a new README? There isn't one. Regards, David -- Dr. David McG.
