This means that later images get blended more than ealier images do. Input images (no overlap) Default settings -wideblendĮnblend blends image sequentially, with the amount of blending seeming to be dependent on both the amount of overlap and the current size of the intermediate mosaic. Other differences in implementation mean that Multiblend is able to blend images which have very little overlap, or even none at all (including images which have gaps between them): The following images show how Multiblend blends images more smoothly than Enblend:Įnblend Multiblend (default) Multiblend ( -wideblend) Due to Enblend's O(n 2) time complexity, compared to Multiblend's O(n) linear time complexity, this speed advantage increases to 300x for a gigapixel mosaic:īased on this exponential difference, Multiblend would take less than a day to blend a terapixel (1000 gigapixel) mosaic Enblend would take 360 years. In testing, Multiblend is about 10x faster for small mosaics. This is where Multiblend really wins out, as all images are (effectively) simultaneously blended:

(…and 716 other possibilities) Enblend Multiblend Multiblend, however, doesn't optimise seams as Enblend does.Įnblend similarly expends a lot of CPU cycles generating a full intermediate image for each new input image, with each intermediate image taking longer to generate than the last as the output image grows. In contrast, Multiblend calculates a unique composite seam for all images simultaneously, using a faster algorithm: Not only is this slow (due to the repeated seaming and Enblend's use of an exact but complex algorithm for seam generation), it also makes the routes of Enblend's seams (and the degree to which images are blended) dependent on the order that input files are provided to it. Optional position adjustment for previous input imageĮnblend blends input images one at a time, calculating and optimising a new seam line for each new input image against the intermediate output image so far. all-threads Use all available CPU threads reverse Reverse image priority (last=highest) for resolving Must be specified as last option before input images no-output Do not blend (for use with -save-seams) save-seams Save seams to PNG file for external editing tempdir Specify temporary directory (default: system temp) cache-threshold= Allocate memory beyond X bytes/ilobytes/ For TIFF output, X may be:įor JPEG output, X is JPEG quality (0-100, default 75)įor PNG output, X is PNG filter (0-9, default 3) w, -wrap= Blend around images boundaries (NONE (default), wideblend Calculate number of levels based on output image size, depth D / -d D Override automatic output image depth (8 or 16) +X: increase number of blending levels by X

Image position adjustment via command line parametersĪbout Multiblend is a multi-level image blender for the seamless blending of image mosaics, such as those created with Hugin, PTAssembler, or PTGui.Rewritten, better quality blending engine.Now properly ignores Enblend's -f parameter.

You have to pay but there is a free trial.ĭoes anyone know if the Gimp works on a mac? Does the mathmap plugin for the Gimp work on a mac? That would be a good option if it works.Multiblend Multiblend Current version (Windows binaries): (676k) Source for Linux/Mac/FreeBSD etc: (48k) Latest changes: I don't use Mac so this is a guess (others can provide better help I am sure).įlexify 2 allows you to do some unique transformations in Photoshop. Or any other trick to generate an alternative projection from an equirectangular pano created on PTGUI?
#PTGUI LINUX SOFTWARE#
Is there any software that allows me to generate control points auomatically on Hugin on OSX? Installing it seems to be a mess, requiring Linux and all complicated things I don't want to know.
#PTGUI LINUX MAC OSX#
I am new on Mac OSX and I would like to use Hugin to try interesting projections, other than Equirectangular.
