Compare histogram features of image files (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 ‘compare’ tool has three input parameters. These are two URLs to the XML histogram files that comprise information about image features. These files are acquired us...

Mp3ToWav Mig+QA (2)

• Download

Migrates Mp3 files from input List to Wav files and performs QA. The QA steps include File Format Validation, Significant Property Comparison and migrationQA file content comparison (all CLI). This workflow matches solution SO4 on the SCAPE opf wiki, see http://wiki.opf-labs.org/display/SP/SO4+Audio+mp3+to+wav+Migration+and+QA+Workflow

Mp3 To Wav Migrate QA CLI List Test (4)

• Download

Migrates Mp3 files from input List to Wav files and performs QA. The QA steps include File Format Validation, Significant Property Comparison and migrationQA file content comparison (all CLI). As this is a Test workflow, the (very large) Wav files are deleted, and only the QA results and log files are saved for analysis. This workflow matches solution SO4 on the SCAPE opf wiki, see http://wiki.opf-labs.org/display/SP/SO4+Audio+mp3+to+wav+Migration+and+QA+Workflow

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...
