Extract histogram features from image file using RESTful interface

Created: 2011-07-01 13:15:37      Last updated: 2012-04-04 08:00:05

The main element of this workflow is a RESTful service designed in the SCAPE QA command line tools RESTful package https://github.com/openplanets/scape/tree/master/pc-qa-toolwrapper-rest. The Github project https://github.com/openplanets/scape/tree/master/xa-rester from Andy Jackson is a basis implementation for pc-qa-toolwrapper-rest package. The QA REST package enables creation of RESTful web service that wraps QA command line tool like ‘extractfeatures’ or ‘create’. The workflow for ‘extractFeatures’ tool has path to the RESTful service as an input parameter. The URL to the input image file and the number of histogram bins as integer are attached at the end of the path separated by '/' character. This workflow extracts histogram features from passed image file. The output is an XML string with histogram data. Also the workflow provides output of the REST service status (200 if successful) and XPath output containing data extracted from XML. The service request example: http://localhost:8080/scape-pc-qa-toolwrapper-rest/rest/qualityassurance/extractfeatures/scape-logo.png/7.
