The current EyesIQ system has a few limitations in terms of performance and accuracy:To be able to stitch images from a 2D microscope slide, the 2D position from one image to another needs to be calculated. This process is called image registration. However, inaccuracy in the image registration algorithm introduces a slight error in calculated image position. As more images are being stitched together, the image registration error accumulates. For example, the image position error is more noticeable when the path of the images form a loop.
