How is a Document Processed when using the ClassifyImage Web Service API?
ClassifyImage web service API that is designed for Developers to classify documents from third party applications without creating batch instances.
It will perform a layout based classification based on the samples (BC??\image-classification-sample folder) you provided in your batch class and return the document type (defined in your batch class) in XML format to you.
So, It does not start a batch instance. It executes the image (layout) classification and returns the results so you can use the result in your your custom applications that are outside of Ephesoft. Since it relies on the document types you create and samples you provide, one of the inputs is Batch Class identifier.
