PTAssembler 6.2.0 released

Post by maxlyons » Sat Aug 24, 2013 9:17 am

I have just released PTAssembler 6.2.0. This version adds support for Multiblend, a blending program similar to Enblend and Smartblend, written by David Horman. David announced this program here a couple of years back, and is a fast alternative to the other blenders.

There are also some improvements and fixes to PTAPicker (PTAssembler's control point picker), the photometric optimizer and masking.

A complete list of changes is:
  • Feature: Added support for Multiblend (alternative blending plugin program
    written by David Horman).
  • Feature: Added option to copy mask region from one image to all others.
    (Right-click on image viewer on Step 3 screen).
  • Feature: Added ability to configure the number of data points that
    the photometric optimizer uses. (Fewer points make optimization process
    more quickly, but results may be less accurate).
  • Feature: Added ability to run PTAPicker in "single-row" mode, for faster
    creation of control points in single-row panoramic images. (hold
    Ctrl key down while clicking the "Auto-Create" or "Generate Controlpoints"
    buttons).
  • Change: Photometric optimizer ignores over/underexposed regions of image
    when calculating photometric (i.e. exposure/vignetting) adjustments.
    this should improve the quality of the results calculated by optimizer.
  • Change: Photometric optimizer "balances" exposure adjustments when exposure
    is optimized and the reference image is auto-selected. This ensures that
    exposure adjustments across all images average to zero (to minimize
    the amount by which any individual image's exposure is adjusted).
  • Bug Fix: Fixed bug in photometric optimizer to make it select more evenly
    distributed points.

PTAssembler (32-bit and 64-bit versions) can be downloaded from this page.

Thanks Max.

I'm looking forward to testing it.

Just to say, the old Multiblend linked to above actually bears little relation to the current Multiblend (http://tawbaware.com/forum2/viewtopic.php?f=3&t=6396 or http://horman.net/multiblend). The old version was a GUI program and the code was more proof-of-concept and not particularly quick (it was only twice as fast as Enblend ;) )
