Version 0.3 adds a "static" parameter - set this to true to make non-animating remaps much quicker.

My script (2.7K video from GP3BE) now opens little bit slower (22 seconds in comparison to 6 seconds with xyremap v.0.2), but it runs MUCH faster - 6.8 fps in comparison to 0.18 fps with xyremap v.0.2. It's almost 40 times faster! Incredebly! Thanks, davidhorman! Perfect filter! By the way, do you have plans to add another interpolations to existing bicubic and nearest-neighbour. Let's say Lanczos or Spline? I think it can make pictures little bit sharper right after conversion, isn't it? |

New version, if anyone cares!
Download beta: xyremap0.4beta.zip v0.4 (beta) Changes include, but are not limited to, the following:
*it incorporates an RPN-to-x86 compiler, for those (if any) interested in such technical details It also now has comparison and conditional operators: "<", ">", "<=", ">=", "==", "!=" each return 1 if true of 0 if false. "[x] [y] [cond] ?" returns x if cond is non-zero, otherwise it returns y. Real example: "10 20 x y < ?" - returns 10 if x<y, otherwise 20. For now there are no boolean operators, but you can hopefully simulate them with mathematical operators. This is a beta, so use at your own risk. Any questions? *tumbleweeds* Last edited by wonkey_monkey; 27th August 2015 at 13:14. |

I've uploaded yet another new version (0.5). It fixes a minor bug (one of the variables was being set to an incorrect value), adds a couple of new RPN operations (which I've now detailed properly here) and the bicubic interpolation is now (approximately) gamma-aware.

Oh, now, stop it, you'll make me blush. It's just nice to know someone other than me is getting some use out of this.
I still feel the whole RPN thing may be a little opaque, so if anyone does have any "how would I do this" or "can I do this" questions... |

A "gallery" of visual effects, with source code (like your first post), would help get us started.
A infix-to-postfix converter (like Masktools' mt_polish) would help code readability a lot, at least for those of us who do not think in RPN. A GUI with realtime preview and code generation would be great, but that's too much to ask |

Fixed Reel.Deel image posts (Reel.Deel, just need change PostImage.org to PostImage.cc)

Well they worked four years ago when he first posted 'em.
An x64 version is still on my list, but unfortunately I've messed around with my RPN library so much that xyremap won't currently compile a working version. Last edited by wonkey_monkey; 13th September 2019 at 11:53. |

At least one of your images (2nd post in fusion thread) has broken Imageshack link, dont know if fixable like PostImage links.
Its enticing to use common library, but any change can kill stuff, so I generally dont use, I usually copy paste relevant stuff and make changes where required. Neither way is ideal.

I believe one could use this filter to simulate a kind of "fisheye scaler" as used in some "smart" TV sets to anamorphically scale 4:3 video up to a 16:9 canvas, where the center remains mostly undistorted, and the borders are pulled to the sides, as if you are inside a cylinder the video gets projected on.
I just need to calculate a convenient formula to resample a 704 or 720 pixels wide centered line to a length of 1024 pixels (I guess a "viewing angle" parameter could control the amount of distortion here). And then transform it into UPN. |
