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...

Extract histogram features from image file (1)

• Download

As a template for creation of image workflows was used xa-toolwrapper project from Sven Schlarb (https://github.com/openplanets/scape/tree/master/xa-toolwrapper). This project enables creation of WSDL web service that wraps command line tool like ‘extractFeatures’ or ‘create’. The workflow for ‘extractFeatures’ tool has two input parameters. The URL to the input image file and the number of histogram bins as integer. This workflow extracts histogram feature...

ToMaR HDFS Input Directory Processing (2)

• Download

This workflow allows processing an HDFS input directory using ToMaR. The "hdfs_working_dir" input port is the HDFS input directory which containes the data to be processed by ToMaR. The "toolspec" input port contains the toolspec XML describing operations that can be used (see "operation" input port). The "operation" input port defines the operation to be used in the current ToMaR job execution (see "toolspec" input port, an operation port used here must be defined in the tool specificatio...
