Matchbox Evaluation (1)

• Download

Matchbox evaluation against ground truth. The evaluation process first creates the matchbox output and ground truth lists. It then counts each page tuple from the matchbox output that is in the ground truth as correctly identified tuple (true positive). Those that are not in the ground truth are counted as incorrectly identified tuples (false positives), and finally, those that are in the ground truth but not in the matchbox output are counted as missed tuples (false negatives). The precision...

Find Duplicates using Matchbox command lin... (1)

• Download

The workflow takes a list of digital documents as input, extracts SIFT features using image processing algorithms, creates dictionary of visual words, generates BoW (Bag of Words) histogramms and finds duplicates. The count of parallel threads can be passed as a parameter. Finally search results are stored in a text file that contains a list of possible duplicates with associated similarity score. This score values are spread between 0 (low similarity) and 1 (high similarity). Image compariso...

TIF to JP2 file format migration with qual... (1)

• Download

This workflow reads a textfile containing absolute paths to TIF image files and converts them to JP2 image files using OpenJPEG (https://code.google.com/p/openjpeg). Based on the input text file, the workflow creates a Taverna list to be processed file by file. A temporary directory is created (createtmpdir) where the migrated image files and some temporary tool outputs are stored. Before starting the actual migration, it is checked if the TIF input images are valid file format instances u...
