Fast median algorithm

[guga]

Hi Guga,

I think I understand what you are doing and an edge detection algo is a lot more useful than just removing water marks, it can also be used for both smoothing rough images or sharpening slightly blurry ones. What I suggested originally was a technique that I have been using for years, close proximity cloning to get the field depth correct and match the texture where possible.



The original on the left, the modified on the right. I used some Russian software to remove the buttons and manually cloned the background to get rid of the insignia. My comment is you can do both as both techniques have their advantages and between them the watermarks you want to remove can be filled in with a texture that maintains the correct field depth.

Very, very good !


The buttons you removed with which software ? You told is a russian, but, what is it ? It seems that what it does is paint over the good areas. If it is this what it´s doing, i´ use a program called inpaint that does a similar thing.


I saw some awesome program that can restore old movies near perfection. It´s called Viva Film Restoration. Unfortunatelly, it uses Cuda, so i can´t be able to give a try.

Take a look on what it does. It´s amazing. Too bad it uses only cuda

Sure, that if we ever succeed to make this algorithm works (even though google designed it only to watermark removal), a simple adaptation can make it work wonders specially because what those other apps does (basically) is calculate the area of the edges where they want things to be removed or cleaned. The main problem i see on such apps is that they uses (in general) huge libraries such as opencv (or cuda, in this case) that are absolutely unnecessary if could simply rebuild the same functions from scratch and improve them to produce the very same result (or even better).

There are other apps  (an old one), such as Diamond Film restoration and PFClean  that also do a good job. The main problem of diamond and PFClean is that it is not perfect and it is sloooowww.

Hi Guga,

The app is called "Movavi Photo Editor 6". It does exactly what I did not need, tweaking pretty girls to look better but its fun to play with. I did the cloning with my very old and now buggy MicroGrafx Picture Publisher as it has exactly the right tools for doing this.

My suggestion was once you get the edge detection algo up and going, try sampling close to the watermark area to get the texture and field depth then selectively clone small parts to get rid of any blurring. I have seen robot watermark removal and some of it is real junk, a blurred mess that stands out very badly due to no compatibility of field depth.

[hutch--]

Something I should add, in reverse of normal video restoration, I have occasionally tried to make modern video look like old very slow frame rate film and while I have software that can add scratches, vignette and convert to either monochrome or sepia at 8 frames a second, its very hard to get it right. Hard to add in the flicker.

Indeed. Sampling closer to the edge seems to be the way to go. The python version seems to do that using a technique called "Poisson reconstruction" that seems to do this. I tried Movavi once, but i quit. personally i´m used to PaintShop pro for image edition, irfanview when i need to decrease the size without quality loss and Inpaint when i need to reconstruct some areas.

For video, i´m used to Sony vegas, plus VirtualDub and now, i´m trying to learn this huge ffmpeg 

If you want to make modern video looks like old, there´s a good forum where people teach doing this using avisynth (forum video help)

The guys there do a great job in video processing. Take a look a this example. (It´s for restoring old movies, not the opposite, but seems good, although i didn´t tested yet)

I could lead you astray here, my JpgTool complete with sauce (whoops I mean source) does that just fine. With input from Marinus and Vortex the GDI+ code works really well.

Wow. Tks you, steve

If you can, please release the source, i[ll like to see how to work with gditools to open image files and grab the pixels data.

Hi guga,

At your service,

Bare Minimum GDIplus code to save different Image Types and PixelFormat conversions:

http://masm32.com/board/index.php?topic=8483.msg92918#msg92918

You can skip "GdipCloneImage" in the sources, it's only used to process the same image over and over again.


Here is a routine to load a bitmap image to memory forced to 32bit ARGB pixels.
Now you have access to the raw ARGB pixels. 
No matter the format of the original bitmap image.

This is how to create a pImage from the raw 32bit ARGB bitmap data in memory

Code Select Expand


I_pBits = the memory pointer to the raw 32bit ARGB bitmap data in memory
I_Stride = I_Width * 4

    invoke  GdipCreateBitmapFromScan0,I_Width,I_Height,I_Stride,PixelFormat32bppRGB,I_pBits,offset pImage


Now you can use "pImage" with one of the routines in GdiPlusColors.zip to save it in the format you like.

Hi Guga,

Using the code by Marinus is a better choice, I converted his and Vortex's code to 64 bit MASM but it would be no joy to convert as the architecture is different between 32 and 64 bit. I have it ready as example code for 64 bit MASM but the procedures are in the library so they can be reused in 64 bit MASM code.

Here is my most recent attempt to emulate old film, its an old stone church in the area where I live. Its almost OK but I have not yet worked out how to do the flickering that very old film had. I want it to look like the technology of the very old movie Nosferatu.

I love that movie.

Excellent work :)   

What program do you use to work with video ? If you use sony vegas  or premiere, there´s a filter called "Ignite Flicker" that you can play with.


Or, you can also try with virtualdub. I remember seeing a flickering filter that works on it. I don´t remember the name because my HD where Vdub was stored, simply fried last month 

But, it do exists a filter for vdub that can also do the flickering for you. Other filters have those large black and white spots simulating a damage on the film which also brings more realism when you want to make a new video looks like and old one. Or even adding some effects of increasing the contrast and blurring a little a couple of frames also makes it looks like something filmed back in the 1910´s.

You could also try decrease the framerate in something in between 16 to 20 fps and later rebuild the video to 29.970.  This would delete some frames and simulate those "stops motions" that old movies does when people are moving, for example. That thing that happens when you see a guy with his hand raised and the next frame it immediately have his hands on the floor

Thank you a lot marinus and steve.

Marinus, what´s the format of the structure"GDIplusBitmapData" ? I can´t find it .

Hi Guga,

I use MovAvi as its more or less useful. It started out a bit "cheap and cheerful" but has got a lot better over time (Software from Novosibirsk in Siberia). For doing the final finishing I use FFMPEG for image sizing, fine control of sharpening/smoothing and bitrate. If you look in the Microsoft 64 bit MASM »Tools & Toys sub forum I have a number of interfaces that use FFMPEG and all you need is to have FFMPEG in your path and they work fine.

RE : The cooked HDD, something I learn long ago was to put all of my HDDs behind a front case fan as disks last a lot longer if you don't cook them.

Btw...The above  guids and values (including yours)  are accessed in GdiPlus at: GdipGetImageEncodersSize and GdipGetImageDecodersSize apis that leads to a internal function called "InitializeBuiltinCodecs".


Those data are stored as a array of structures pointed from inside that InitializeBuiltinCodecs function. I presume it is something like: ImageCodecInfo. Not sure it if is documented, but, anyway, i named the structure to what it seems to be doing as:

Code Select Expand

GugaImageCodecInfo struc
        CLSID dd ?
        FormatID dd ?
        CodecName dd ?
        FormatDescription dd ?
        FilenameExtension dd ?
        MimeType dd ?
        Version dd 4 dup(?)
        Signature dd ?
        SignatureReserved dd ?
        pInstanceFunction dd ?
GugaImageCodecInfo ends



The above structure, btw, is almost equal to this:
