VDM 2012 Algorithms.MatchPattern2 SP1 has the image of the model

My application requires (acquisition and treatment) fast enough repetitive image<100ms per="" cycle).="" kind="" of="" "realtime"="" processing,="" i'd="" prefer="" not="" doing="" post="" image="">

Currently the image processing takes ~ 200ms per cycle (mainly grey filtering image).

~ 150ms of this time is taken by load images from disk or cloning model images of the model (using the flatten/unflatten visionimage).

The reload or cloning is that the Algorithms.MatchPattern2 has the image of the model during execution, i.e. I have to reload or clone images model each acquisition/processing cycle.

Ideally, configuration I would like to provide 1 x set of images of model for processing application that is reused (without cloning) each treatment cycle to a time of 50ms ~ process.

Patches or a workaounds?

Thanks for the reply Rob.

Note: I use .net VDM and coding in c# libraries.

My purchase is decoupled from my transformation. The main reason to mention the acquisition should provide a bit of context to my question.

I first thought that my large KING was originally the processing time increased (initial duration process = ~ 230ms). Then I reduced the sizes of my Kings and improved the execution time = ~ 190ms.

I am currently creating a model images table and passing to the function (essentially by 9 x 1 x OCR and correspondence to the model) image processing.

When I remove the model image cloning code (visionimage flatten/unflatten), the image processing function runs in 50-60ms but runs only once. On the second cycle of the excution, it throws an exception.

"Cannot access a deleted object."
«Object name: "NationalInstruments.Vision.VisionImage".»

I'll try MatchPattern 3... My current version doesn't have a MatchPattern 4.
