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...

Hadoop Large Document Collection Data Prep... (1)

• Download

Workflow for preparing large document collections for data analysis. Different types of hadoop jobs (Hadoop-Streaming-API, Hadoop Map/Reduce, and Hive) are used for specific purposes. The *PathCreator components create text files with absolute file paths using the unix command 'find'. The workflow then uses 1) a Hadoop Streaming API component (HadoopStreamingExiftoolRead) based on a bash script for reading image metadata using Exiftool, 2) the Map/Reduce component (HadoopHocrAvBlockWidthMapR...

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...
