Mathcad Add-Ons: Image Processing Extension Pack

Examples

 

The Image Processing Extension Pack provides a powerful solution for iterative exploration and investigative analysis. With its extensive image processing, analysis and visualisation capabilities, this Extension Pack is ideal for research scientists and engineers, design engineers, system analysts and image specialists working on imaging or multimedia product development. It is also a valuable tool for students studying electrical engineering or computer sciences.

 

This robust Extension Pack provides a total of over 140 built-in image processing functions. Among the highlights of this new version are over 50 new functions. Plus, you get an interactive image viewer for easy manipulation, new file formats to make it easier to work with other applications, and expanded document with templates and application examples. And because the Extension Pack becomes part of your Mathcad desktop, you can use it to create publication-quality technical documents, graphs and presentations.

Highlights of the Mathcad Image Processing Extension Pack

  • Filtering – denoising of images
  • Morphology – to achieve sharper image characterizations for object identification
  • Edge Detection – image enhancement for object identification
  • Segmentation – for analysing specific regions/clusters of interest
  • Feature Extraction – to quantify object features such as length, size, other dimensions
  • New image viewer with interactive image manipulation capabilities (zoom/pan/crop,
  • brightness/contrast, rotate/flip/transpose, etc)
  • New file formats ( BMP, GIF, JPG, PCX, TARGA, PGM, TIFF)
  • Expanded Electronic Book documentation and application files

What do our Customers say about us?

You have set a benchmark standard that many other companies should aspire to.

JS, Chippenham, UK

Good balance of basic information and practical tips for the more experienced

DV, Manchester, UK

The training session has been invaluable. Your expertise and your patience are exemplary. It cannot be easy to teach a 75 year old new tricks but you have done so with the utmost understanding. The software is extraordinarily powerful: you have explained how to use it in simple and understandable terms.

SF

Our Account Manager, Stephanie, was fantastic in dealing with our questions and my colleague’s concerns (many thanks Stephanie!) and your colleague Joe has provided invaluable assistance to my colleagues and myself during our initial and extended testing phases of Reference Manager.
