TCannyMod

[Chikuzen]

Canny edge detection filter for Avisynth2.6x based on tcanny by tritical.

slow (because almost all processings are performed in the floating point), but faster than tcanny about 1400% to 2500%(by the favor of SSE/SSE2 and smart hysteresis algorithm).

binary: TCannyMod-1.2.0.zip
source code: https://github.com/chikuzen/TCannyMod/

requirement:
* Avisynth2.6.0/Avisynth+r1576 or greater
* Microsoft Visual C++ 2015 Redistributable Package
* WindowsVista sp2/7 sp1/8.1/10
* SSE2 capable CPU

EDIT:
2016-05-25 update to 1.2.0

Nice , am I right if I'm guessing this as step 1, before porting this to [VapourSynth] GenericFilters ?

And more of a curiosity question, would this plugin be even faster if AVX optimization was added considering it's floating point heavy?

Dunno.

Chikuzen, if in your VS project settings you deselect any runtime - your plugin will be linked against static runtime, eliminating dependency for the small size cost.

The reason I do not static link MSVCRT is for security and performance.
It is a foolish act to release a new binary whenever a bug is found in MSVCRT. The developer who likes static link is an irresponsible person who does not consider such a thing.
And in my experience, dynamic linked binaries are a bit faster than static linked.

I used this when I didn't have an AVX CPU.

[Chikuzen]

update to 0.1.0

* fix some typo
* add new function 'GBlur'
* add new argument 'sobel'
* sigma allows to set to 0 (do not blur before edge detection)

[Chikuzen]

update to 0.1.1

* fix crash when sigma is too large.

It seems using left Crop before TCannyMod will return error "TCannyMod: Invalid memory alignment".

This script returns error

BlankClip(1000, 1920, 1080, "YV12")
Crop(4, 0, 0, 0)
TCannyMod()

While this one works

BlankClip(1000, 1920, 1080, "YV12")
Crop(0, 4, -4, -4)
TCannyMod()

Try

BlankClip(1000, 1920, 1080, "YV12")
Crop(4, 0, 0, 0,align=true)
TCannyMod()

updated to v1.0.0

[Chikuzen]

update to 1.1.0.

Hi Chikuzen
I question here.Avisynth wiki

EMask with default settings is
GBlur (sigma=1.5, gmmax=50.0, chroma=0, sobel=false, opt=-1)

Should this be corrected "EMask"

fixed

update to 1.2.0

- Set filter mode as MT_NICE_FILTER automatically on Avisynth+ MT.
- Use buffer pool on Avisynth+ MT.
- Disable AVX2/FMA3/AVX code when /arch:AVX2 is not set.
- Disable AVX2/FMA3/AVX code on Avisynth2.6.

A little question about things like this in your code :

#if defined(_MSC_VER)
    __cpuid(array, info_type);
#else
    __cpuid(info_type, array[0], array[1], array[2], array[3]);
#endif

What compiler from VS are you switching from ?
Is it Intel compiler, or another ? In what case do you put the Intel compiler ?

It's GCC (and Clang).
That code was written to use it by vapoursynth plugins originally.
Since avisynth's GetCPUFlags() does not support AVX2 and FMA3, I use it on avisynth plugins too.

Don't know if this is the right place to post (or maybe in the avs+ topic?) but I get an "Avisynth open failure: system exception - access violation" when just loading the plugin (on latest dev avs+ r2397). The strange thing is that this happens only on x86 because the x64 version seems to work fine (at least it load the plugin).

[kgrabs]

actually i got an access violation too, after upgrading to Avisynth+r2172 MT i386 from Avisynth+r1576, that went away after i removed tcannymod.dll from my autoload folder

[pinterf]

I think the plugin uses IScriptEnvironment2 avs+ interface, that is avs+ version dependent, and has been changed since the last build
