In general video streams are compressed in time domain. If we send one frame as an event this will not be achieved and the required bandwidth will be higher. Instead if the video stream can be chunked and decompress inside the server / engine, bandwidth could have been saved.
BTW we can use the same input adaptors to get videos to BAM and do some batch processing if map-reduce implementations can be found for computer vision algorithms like http://hipi.cs.virginia.edu/ *Maninda Edirisooriya* Senior Software Engineer *WSO2, Inc.*lean.enterprise.middleware. *Blog* : http://maninda.blogspot.com/ *E-mail* : [email protected] *Skype* : @manindae *Twitter* : @maninda On Thu, Nov 13, 2014 at 8:32 AM, Srinath Perera <[email protected]> wrote: > Adding dev@ > > Hi Suho, Mohan, > > Open CV (computer vision library) let you train and build a model that > generates an XML file that can be used from a java program to classify > video streams (e.g. detect an human, vehicle). > > Idea of the project is to write an CEP extension that takes the XML file > and detect vision detection.
