The invention relates to materials and methods for producing equivalents of tissues of the ocular surface, especially conjunctival tissue equivalents. The method of the invention involves biopsy of an appropriate tissue, primary culture in a certain medium, proliferative culture in a second medium, and differentiative culture in a third medium. The tissue equivalents are typically grown upon a substrate, typically amniotic membrane, which provides ease of handling as one advantage.

The invention is a process to compare two digital images (and usually more) and to identify objects in each image. After object identification, object descriptors are formed. The object descriptors of the objects in one frame are compared to those of objects in the second frame, allowing the tracking of an object in the two frames. The movement of each tracked object within the two frames is quantified, and the second frame is corrected to account for the object's movement.
