Advantages of our software over current software in the market

Current market software uses either:

  1. a noise filter to reduce image noise for a better contrast-to-noise ratio
    (the trade-off in this approach is the removal of high spatial frequency information), or
  2. the digital enhancement of subtle contrast, or both.

Both of these approaches are unable to pin-point the true edge positions of edge-profiles to close the blurred gap caused by the Penumbra-Spread Effect for accurate measurements.

Our software uses the unique De-Convolution Technique to pin-point the true edge positions to sub-pixel accuracy (refer to Publication #18).

Edge enhancement is achieved by the removal of the Penumbra-Spread Effect via sub-pixel transfers, without any trade-off loss in signal causing an increase in image noise (and we also have the option of a noise filter if and when required).

Distortion correction and absolute calibration algorithms are also available for X-ray radiography images, enabling accurate measurement of defects for condition monitoring in Non-Destructive Testing.


Windows XP & Windows 7 versions of the IETech-NDT and IETech-MED are now available.

  1. IETech-MED (view media) - providing image analysis & enhancement, and Computer Aided Detection (CAD), for medical applications.

  2. IETech-NDT (view media) - providing image analysis & enhancement, and Computer Aided Detection (CAD), for Non-Destructive Testing (NDT) & Enhanced 3D-Finite Element Analysis in industrial applications.

  3. IETech-FPM - (Fingerprint Matching Algorithm) - Ensure 100% matching efficiency (i.e. 0% false matching & 100% true matching) via a sensor. Used as e-lock & e-key in applications such as to replace PIN number for ATM, secure banking via mobile phone, iPad, counter check-in card reader, immigration control, Internet fraud prevention, prevention of hacking into mobile phone, prevention of hacking into bank account, etc... (Status - research and Sequential Processing both have been completed successfully, need to develop Parallel Processing to sub-second in processing speed).

Other options

  1. An Image Analysis Service.

  2. A C/C++ library, providing image analysis and enhancement, is available for possible incorporation into existing software, under licence. Contact IET for further details.
