A common issue in fingerprint identification is the obstruction of useful fingerprints by periodic noise. The periodic noise pattern, in the form of lines, dots, or even a mesh fabric pattern may be minimized or removed through the use of the Fast Fourier Transform (FFT) feature included in our Image-Pro image analysis software platform.
FFT allows the user to quickly identify and view the periodic noise obstructing the finger print image. The pattern, once identified and marked, can be removed from the image to reveal the finger print detail.
The importance of firearm and forensic tool mark analysis has been well recognized. Image-Pro includes tools for the efficient side-by-side comparison and analysis of images using either the Live Image Compare View or the comparison of previously acquired images.
A full suite of documentation and reporting tools is available once the analysis has been completed within Image-Pro.
Carbon, natural, or synthetic fibers are used in a variety of manufactured goods and industries for identification purposes. The Fiber Separation and Fiber Thickness APPs for Image-Pro can be used to measure fiber length and thickness - even when analyzing overlapping fibers.
Using Advanced Fast Fourier Transformation analysis (FFT), the orientation of fibers may also be determined.
