Image Processing

  • Stumbled on to a well done video from Computerphile called "How Blurs & Filters Work", which I thought some of you may find interesting. Discussion centers on what an image kernel is and how they're used in image processing. Video is under 8 minutes and is embedded after the break. Enjoy.

  • From teaching classes over the years I frequently hear that many agencies are using Photoshop 6 and 7, Paint, Photoshop Elements, Microsoft Picture It and other applications due to the lack of funds to purchase upgrades. There is nothing wrong using some of the older versions but there are several functions that the older versions do not support, like high bit depth processing, limited color space/model options and the lack of more sophisticated image processing algorithms (de-convolution, pattern removal using FFT).  I also understand that many agencies who would love to have PS CS3 Extended with all of the great plugins that have been developed will never get the funds to make these purchases.

    One solution to the funding issue is Image J ( Image J is a free, open source application provided by the National Institutes of Health (NIH).  I not only have used this application for case work but to learn more about digital image processing algorithms. Image J is a very robust image processing and analysis tool set that has been referred to on the FVA list serve and recently in the book written by George Reis. This write-up is not a tutorial about Image J, it is meant to provide information about the application that may assist some readers.

  • Another Jem from the Photoshop Jedi Master Deke McClelland. Think a discussion on Photoshop's Image Size tool is too basic for you? Fear for you I do, for that is the mindset of someone leaning toward the dark side.

    "The essential Image Size command lets you scale an image on screen or in print. In this week's Photoshop Top 40 Countdown episode, Deke explains resampling and resolution, both of which affect the core quality of digital photographs."
