|  The IPT AutoOptimizer™ is an image processing device that interfaces to various scanners and produces a thresholded black and white output that is superior to the black and white image created by the scanner alone. Processing Speed 25 million pixels per second 178+ images per minute at 300 dpiFeatures of the AutoOptimizer™ PC Interface for AutoOptimizer™ Control Smoothing Filters Two-Dimensional Dynamic Thresholding Automatic Edge Detection Edge Filtering Line Filtering Despeckling Black and White Level Background Suppression 10 User Defined Presets Hand Held Terminal included for serial control of AutoOptimizer™Enhancement Parameters for the AutoOptimizer™
PresetsPresets are sets of parameter settings which can be saved and recalled with a single command. The settings shown above constitute the factory s Preset 0. Presets 0 - 9 are available for storing parameter settings. For the typical scanning job, most if not all of these parameters do not require adjustment. For atypical and very poor-quality documents, these added layers of parameters serve to provide the user with the tools needed to achieve optimum enhancement in most any circumstance. The ability to save and recall sets of parameter settings can greatly enhance batch processing of difficult documents.Parameters: A Brief Description of EachBrightness: Defines the lightness level of the document. Auto, fixed or outline settings are available.Sensitivity: Controls the edge detection. Auto, fixed or OFF settings are available. Filters: Controls the black & white despeckling filter. Contrast: Sets the intensity level of the lowest contrast feature to be detected by the AutoOptimizer™. Inverted: Inverts the image (translates black pixels to white pixels). BWFilt: Incorporates hole removal, secondary despeckling and edge smoothing filters. ON or OFF settings are available. Afilt: Performs the complementary function to the Filters parameter. Wlvl: Overrides the automatic brightness to suppress background. Smth: Provides Gaussian smoothing filtering. AvgB: Fine tunes the automatic brightness level. Low, Medium, or High settings are available. Thck: Controls line thickness and noise. WinSz: Controls the amount of detail detected by the AutoOptimizer™. 7x7 or 5x5 settings are available. Thr1 & Thr2: Fine tunes the thickness parameter. AutG: Provides automatic contrast adjustment. ON or OFF settings are available. Blvl: Overrides the automatic brightness to preserve solid large black areas on the image. Offs: Fine tunes automatic sensitivity. Currently Supported Scanners Mekel XL400/460, M500, M560 Kodak IMAGELINK 900 Series, 500 Series, 5500 Ricoh IS410, IS420 Fujitsu All 309x Simplex & Duplex scannersOCR Improvement with AutoOptimizer™The IPT AutoOptimizer™ is ideal for preprocessing images intended for Optical Character Recognition. The images below illustrate the enhancement power of the AutoOptimizer™ when dealing with typical printed or hand written text. This type of form is standard for many diverse applications in various fields. The image on the left is a portion of a standard scanner's output with no enhancement. The image on the right is of the same section of a page, but this time the output is from the AutoOptimizer™. The enhancement achieved enables any character recognition software to provide optimal results.We have compiled a set of statistics on the improvement offered by our AutoOptimizer™ when used in conjunction with OCR software. The test was performed on two different scanners, and at two different resolution settings. The graphs shown below illustrate the improvement in results obtained with enhancement provided by the AutoOptimizer™. The vertical axis represents the correctness of the OCR software's output compared to the actual page, zero being entirely incorrect, one being perfect.The horizontal axis represents different documents, numbered one to ten, and a final cumulative average labelled "overall" on the far right of each graph.
