Detect compressed TIFF files and remove th... (3)

• Download

The workflow takes a list of TIFF images as input, identifies the "Group 4 Fax" comressed TIFF images and converts them to uncompressed TIFF images using convert. Finally it characterises the converted image. This version of the workflow replaces the web services of the original workflow with tool services.

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...

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...

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...

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

• Download

This workflow reads a textfile containing absolute paths to JP2 image files and converts them to TIFF image files using Kakadu's j2k_to_image command line application (http://www.kakadusoftware.com). 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 converting the files, the JP2 input files are validated using the SC...
