Description copied from class: CvStage

Perform an operation in a pipeline. Typical implementations will call CvPipeline#getWorkingImage(), perform some type of operation on the image and will return a Result containing a modified image and model data about features found in the image. If the stage only modifies the working image, it is sufficient to just return null, and this will typically be the most common case.

Specified by:

process in class CvStage

Returns:

Null or a Result object containing an optional image and optional model. If the return value is null the pipeline will store a copy of the working image as the result for this stage. Otherwise it will set the working image to the result image and store the result image.

Throws:

java.lang.Exception
