Article: Estimation of parameters of foraminiferal test geometry by image analysis

Outline analysis cannot be expected to yield good results when applied to foraminifera because of the uncertain relationship between outlines and three-dimensional morphology. Foram test morphology can often be described efficiently by means of a suite of geometrical parameters controlling chamber shape, size and accretion. These parameters can be obtained from images by an iterative optimization technique. The method has yielded good results when tested by application to simulated images.
