THE FISH4 COMPARATOR IS DESIGNED TO SUPPORT THE COMPARISION AND IDENTIFICATION OF FINGERPRINT IMAGES: AVALIABLE AS A CD OR EASY DOWNLOAD
The FISH Comparator scans latent images, exhibits, 10 print forms and known sheets. The application also loads camera images with automatic photograph scaling. Colour images are converted to black/white and levels adjusted.
An automatic scaling algorithm, embedded in the Comparator, scales the image; simply clicking on the Scale Image button in the application activates this function. The image can be further enhanced and magnified.
The FISH interface is designed to enable the fingerprint specialist to quickly prepare fingerprint images for comparison. A range of buttons provide for enhancing the fingerprint image along with the ability to crop and save a specific fingerprint lift or area of the image.
More buttons in the comparison panel, enable you to chart the comparison points between the two fingerprints. These points, displayed as a combination of filled or empty boxes and circles are in four colours red, green, blue and purple. The transparency of these shapes changes by clicking the boxed numbers – 0, 3, 6 or 9. Areas and regions are highlighted using the brush or region buttons.
The Comparator is designed to support the high quality images required for fingerprint identification.
The Comparator supports the following file formats: TIFF, JPEG, JPEG2000, PNG, BMP, Cannon RAW (.cr2), Sony RAW (.arw), Nikon RAW (.nef), Fuji Film RAW and Hasselblad (.3fr).
FISH COMPARTOR OVERVIEW
The main goal of the fingerprint expert is to deliver reliable conclusions. With fingerprints of good quality and ten prints, there is generally no room for interpretation and error and hardly any chance of mistaken judgement on identification.
However the poorer the detail at hand, the greater the role of the expert becomes and they need to compare, judge and validate.
Mistaken identifications have some common causes; the fingerprints under examination are of bad quality and/or there is time pressure to achieve a match.
NO TWO COMPARATORS ARE THE SAME
The fingerprint identification process follows several stages of activity in order to achieve sound decision-making. This process follows a pattern of stages. These are the stages; Comparison, Evaluation, Decision, Verification and the Conclusion.
Most fingerprint comparators focus on the algorithm features built into their systems rather than assisting with the process of identification.
THE FISH APPROACH
FISH comparator places its emphasis not only on the algorithms but also more importantly on the processes involved in fingerprint comparison.
This approach supports fingerprint bureaus, which document all of their procedures and processes undertaken to accomplish its analysis work.
FISH Comparator scans latent images, exhibits, 10 print forms and known sheets. The application also loads camera images and photographs can be automatically scaled. Colour images can be converted to black/white and levels adjusted
The Comparator, designed to work on notebook and desktop computers, delivers its full effectiveness when used with a dual screen hardware configuration. This enables you to work with the images on one screen whilst using the other to manage image files and case folders.
The menus and layouts of the screens in the Comparator emulate the process of fingerprint image collation, mark extraction, level 1 recommendations, level 2 ridge analysis and marking up.
