Motion detection software required

[url removed, login to view] is looking for a programmer / consultant to help develop a motion detection component within a video security system.

About us:

[url removed, login to view] offers an online video recording, monitoring and analysis services.

We work with regular IP cameras, each 2 seconds a snapshot (.jpg file) is made and stored in Amazon S3.

Then these snapshots must be processed with various algorithms to detect motion.

We need a service that provides an XML Web Service (SOAP) API with a method which

Receives a set of records where each record is:

Id int - Snapshot Id

CameraId int - Camera Id

Url string - Snapshot S3 Url

MdAlgorithm string - an identifier of the algorithm used

MdArea int array[4] - a rectangle area on the image, top left, bottom right

MdSettings - string, xml - settings specific to the algorithm used.

The service downloads snapshots based on their Url, processes them with the algorithm and settings defined. Returns the result.

The result is:

A set of records where each record is:

Id int - Snapshot Id

MotionLevel number - a level of motion detected

We expect from you to get a description of the algorithm you will use, its settings, what they mean, their allowed range of values. These settings will be passed in the MdSettings parameter as xml (xml structure will be negotiated)

We also expect to hear from you the terms and the price

Its much preferable that programming is done in .NET (C#).

A typical snapshot dimensions is 640x480 with size of ~50Kb, however they may vary. From some cameras we receive snapshots 1024x768 with 180Kb size

Motion detection is done on the series of images. We do not plan run MD on video yet. 

There is no limits on a type of movement. There can be anything - vehicles, people, animals, doors opening.

As a result we should receive the fully compilable source code

i have developed a similar project that detects motion within a set of images, it needs some costumization to meet your needs but it will fullfill them.

I have several years experience with C # and multimedia development. Moreover, it is my turn nearly finished, just missing the API, as well as a few optimizations.
