Improved ABBYY Camera OCR technology enables FlexiCapture Engine 10 to achieve better results from photos through enhanced removal of motion blurs, noise in color photos, and geometrical distortion from an image.
Small Shelf Dimensions: Automatically loaded lyophilizers tend to have a relatively large number of relatively small shelves so that the tolerances of individual vials do not build up to cause geometrical distortion to the pack of vials during its transfer onto the shelf.
Enhanced Image Preprocessing Tools - improved algorithms for geometrical distortions correction, new auto-cropping and background lightening features, and better ISO noise removal ensure more accurate recognition results, especially when documents are captured with cameras in mobile devices and processed in an OCR back-end system.
Their excursions reveal a variety of startling effects -- geometrical distortions, temporal shifts and color changes--that defy intuition.
