vcm a new plugin with many functions

[ChaosKing]

Images are allowed! I can send you an example / small tut later.

Look here is your html code + a image on github: https://thechaoscoder.github.io/pagestest/
Image url https://thechaoscoder.github.io/pagestest/unnamed.png

I added a branch "homepage". You just choose this branch in your github repo settings and github will use it as the root folder to serve html pages. Repo: https://github.com/theChaosCoder/pag.../tree/homepage

I will upload a short video later on how to do it.

EDIT
You could also stay on avisynth.nl but host only the images on github. Basically what zorr suggested with an external img hoster.

You can link to the images without any ads. For example if you look at the first post in this thread the images are all hosted on postimages.org.

And like Chaos said Github is also an option. But you just need to figure out what works best for you.

Took a bit longer but here's a quick how to setup github pages.

* The "myhomepage" branch is optional, you could also just use "main".
* I just found out you can even drag and drop a folder with all your images in the upload box thingy!
* There a some good and free git GUIs like "GitHub Desktop" where you can clone, pull and push with just a mouse click.


Editing in ScreenToGif is not the best experience

[ReinerSchweinlin]

Some PNGs could be reduced in size with some PNG Optimizer - but 100MB eventually will be not enough

If you want something traditional, I could give you some space to host stuff - not using it myself, so what better use than to support such fine filters I would gladly help you out!

[vcmohan]

Many thanks. I am examining my page and finding some unnecessary images. I will remove them and optimize rest. many thanks once again.

@vcmohan: Any hint in how to convert a defish(fov=114,scaling="fitxy") in an equivalent vcm.DeBarrel(..) call?

[vcmohan]

I have not really thought about that. But may be try with a square sized frame and debarrel with relatively higher values for a and b. I am not sure it will work. I will try.

[Selur]

I will try.

Thanks, I keep my fingers crossed, since I would really prefer to use Vapoursynth with vcm.DeBarrel instead of Avisynth with defish to drop the Avisynth dependency (which would allow me to do this on Linux and MacOS), but I now have spend quite some time and I don't seem to be anywhere near the results I (so easily) got with defish.

The problem with the input is the center of frame is not the center of the fish eye. Need to correct for that first. As the fish eye looks like a circular photo, the value of c be 0.5 with a and b at zero. Sorry I misguided you. I also added borders on left, top, bottom and right for centering and for accommodating the corrected image. Finally I cropped to be equal to that of the defish_eye image seen in the link.
the script used is
<code>
ret = core.std.AddBorders(ret,left = 100, right = 100, top = 100, bottom = 740)
ret = core.vcm.DeBarrel(ret,abc =[ 0.0, 0.0, 0.5],pin = 0)
ret=core.std.Crop(ret,left = 60, right = 60, top = 40, bottom = 740)
</code>

Nice! Thanks!
Avisynth with defish(fov=114,scaling="fitxy"):

defish looks extremly cropped, is this normal?

[kedautinh12]

Can you share me original picture to compare??

[Selur]

Can you share me original pickture to compare??

Original pic was linked in the thread I linked to, you can download it from https://mars.nasa.gov/mars2020/multi...Z02002_01_295J

defish looks extremly cropped, is this normal?

Not sure whether it's normal, but since it by default keeps the input resolution it's to be expected to crop quite a bit.

[Selur]

btw. when using:

defish(fov=114,scaling="fitxy", scale=0.5)

you see why the cropping is so strong:

Success to port script to avisynth x64, thank vcmohan very much

I'm testing vcm.F1QLimit and noticed some oddities.

• The max value of span is 99, with bigger values I get error message "F1QLimit: limit percentage value can be 0 to 99". I tested with 1920x1080 source so the max should be 1920/8 = 240.
• Documentation states that frequencies should be at least 10 larger than span but on some cases it needs to be 11 larger. For example span=90 and freqs=[100] gives error message "F1QClean: freqs must be between 10 + span and nuquist - span". Changing span to 89 or frequency to 101 makes the error go away.
• The max frequency should be 512 - span but if span is even then the correct formula is 512 - span - 1. For example with span 6 the max frequency is 505. Does even span make sense, should it always be odd?

As my laptop was and still down since last week, I did not see this comment. It looks like the problem is in floating point and integer conversion. I will rectify It as soon as I get either a new battery pack for my laptop or buy a new one(Expensive)

At last I could get most of data into my new laptop. The documentation for these two filters (F1QClean and F1QLimit) are revised. Please check now. Thanks for pointing out the errors. regards.

@sl1pkn07: The missing file is inserted now.
