Recoloring
There is a thread in this forum with subject as "Colorization code used as denoiser?". It is actually discussing how to color or recolor an image. In one post E_Male suggested renaming the thread to correctly convey the meaning of what is being discussed there, but probably no one seriously took notice of it.. So I deliberately opened another thread to reflect it. Hope I did not violate any rules of forum.
I also have been working on a (re)coloring process. For this I have created a plugin 'coloreds' (will change to recolor or so) with functions named TemplateMaker, colorbrush, colorpencil. I am adding to these ColorFills and drawlines functions. I am very close(?) to finish, but can not say when as so far I tested with a simpler image. ColorPencil takes coordinates of a point in an area and its color as an array. ColorBrush takes coordinates of straight lines, and color as an array. The main work is in formulating a template to demarcate an area to be colored. As with any recoloring attempt more time is taken to decide on various parameters and therefore the actual time taken becomes mostly irrevelant. However I timed my script and i get about 1.5 fps.Since I started with a colored image, this time includes conversion to Grey scale,converttoYUY2 also. I work in YUY2 only but will be able to do in RGB (I hope) My script runs like this Code:
loadPlugin ("E:\TransPlugins\bin\Coloreds\Release\coloreds.dll") loadPlugin ("E:\TransPlugins\bin\Grid\Release\Grid.dll") #---------------------------------------- DirectShowSource("F:\TransVideo.avi").trim(140,0) #converttoRGB32() #r24=converttoRGB24() #r32=converttoRGB32() YUY=converttoYUY2() #YV=converttoYV12() a=GreyScale(YUY) # below good for stars, fireworks, wick, flame t=TemplateMaker(last,1,100,"e3", 88, black=true) # for stars colorPencil(a,1,100,t,5,80,$3f9f,120,80,$5f0080,266,80,$3f00,410,80,$1f004f, 580,96,$ffff,715,62,$3f9f) # for fireworks body colorPencil(last,1,100,t,130,400,$7f5000, 80,420,$7f5000, 170,390,$7f5000) # for wick colorPencil(last,1,100,t,245,360,$2f7000,220,327,$2f7000) # for flame center colorPencil(last,1,100,t,320,370,$1f5f) # for outer flame #colorbrush(last,1,2,t,300,340,360,370,$FF3030,300,340,320,420,$FF3030) # for wickets and all area colorPencil(last,1,100,t,2,400,$1f5f00,40,340,$1f5f00, 380,440,$1f5f00,500,420,$1f5f00,710,250,$1f5f00,225,400,$1f5f00) colorPencil(last,1,100,t,430,115,$1f5f00,540,110,$1f5f00,660,100,$1f5f00,238 ,360,$1f5f00) Original: GreyScale: Recolored: As can be seen there are some spots which are not colored. They can be filled easily with colorpencil function. But I am having this problem which in another thread traversing a closed area, I explained. The solution suggested I did not understand yet. I will be greatful for any suggestions observations. Last edited by vcmohan; 4th May 2005 at 10:51. |

first of all: sorry for not having done the plug-in based on ming yang's colorizing code, yet
it's finished in my head, but time and energy are low would be nice to have a look at your code but if you wanna keep it to yourself until your happy with the result i'll understand that btw, what algo do you use? |

Not having an interactive environment slows things terribly to arrive at various parameters. However I am thinking of learning to make a plugin for virtualdub for getting at parameters. My code is part finished and not in a condition to release. Just testing to make it work for allmost all situations. |

Further I have tested my plugin on a sunset
my script for processing is simple enough. script and results:- loadPlugin ("E:\TransPlugins\bin\Coloreds\Release\coloreds.dll") #loadPlugin ("E:\TransPlugins\bin\Grid\Release\Grid.dll") #---------------------------------------- DirectShowSource("F:\TransVideo.avi") YUY=converttoYUY2() a=GreyScale(yuy) n=20 s=200 y=TemplateMaker(a,s,s+n-1,"c1",90,0,0,true,225,0,0) #Grid(y,s,s+n-1) # sun and surrounding red clouds, reflection x=colorFills(a,s,s+n-1,"rect",0,0,a.width-1,a.height-1, false,$BA673d,"allxy", y,true) # darker clouds x=colorFills(x,s,s+n-1,"rect",0,0,a.width-1,320,false,$996834,"allxy",y,false) # sea x=colorFills(x,s,s+n-1,"rect",0,320,a.width-1,a.height-1-320,false,$3b5444,"allxy",y,false) reduceby2(x) # Grey scale Image # Recolored image, not very pretty but not bad for first attempt. # Original color Image I have some problem in selecting appropriate colors. The HTML colors which Irfanview indicates does produce strange hues on my lcd screen. May be I need to use R, G, B colors as seperate parameters. There is a need to have a reference large pallette of colors. |

I have made a little more progress on my recoloring project. Here are my script and results. I would appreciate critical comments and suggestions. As mentioned in my earlier post my scheme depends upon mask creation to separate out objects. (it can be grey values, edges, or lines drawn or a combination of all. Linear variation with frame numbers of colordrops and other functions ease in scripting for moving objects. Below is script and results.

Some of them have test facility for parameter value selection. Grid plugin is used to read off coordinates for input. # following script is for recoloring.

I have attempted to color a greyscale image derived from an color photo of a birthday party held in a open lawn. There are a number of children and adults, balloons cake etc along with other items.
As can be seen I have been to a large extent successful. I find that a lot of patience and time is needed. May be a number of persons working parallel on different scenes can create a colored movie out of a black and white original. I use grey scale values and edge detection schemes to demarcate areas. I found that both sobel, prewit even with laplace combination do not give usable demarcations for this purpose. This may be due to almost insignificant level changes at certain places. This forces manual intervention by way of extending demarcation lines. I have also some difficulty in treating the edge itself. It remains and sometimes seen. Grey scale value itself is a better demarcator than edge detection in my experience. Below are the images. Grey Scale colored original Code:

These could be taken care of by manual intervention by drawing boundary lines. It took about 170 lines of script to acheive this and two weeks of 6 hours a day work to get this. But by experience one can shorten this very much. I have also used part of time to fine tune my software. The processing time is about 2 seconds per frame. Last time I reported in haste a problem which I attributed to Avisynth and later found to be a bug in my plugin. But this time I ran into one which is strange. Before I attribute it to Avisynth I will describe it. In the last fewlines I used a maskmaker function starting from frame 9 itself. Then I started to see some old frames as output, and no action occuring. If my plugin is at fault then I should get output of cdchair. But I get a frame about 50 statements back. This function stops at frame 49. If I go past 49 and reverse frame by frame in virtualdub I suddenly start seeing the correct frame processed properly. After changing start frame number to 10 I get a correct process. This is strange as I use this very function over 20 times in my script without any problem. Ofcourse I will check again and again before blaming Avisynth. |

how's your work going?
do you feel you could release the filter/source anytime soon? i fixed 2 stupid bugs in MYcolorize (my fault) and i guess i'll soon have a releaseable version (doesn't mean it'll very usefull, but a good start) i wonder if we could improve the results with combined effort interested? |

progressive images at upper threshold at increasing grey value: image for a low grey value as threshold: image with an intermediate grey value as threshold: image fully processed: I am a bit (lots) disappointed at the results. The recognisable parts in the earlier stages are due to limiting to certain grey values and not due to segmentation by watershed function per se. Literature indicates that this "watershed" oversegments often. May be will be useful for recoloring cartoons rather than real images? I would very much appreciate comments or suggestions on this. I have also added several other features like thinning, skeltonization, ridges and valleys to morpher function. Quote:

This plugin looks amazing... I never thought this would be possible with avisynth...

but it's another very expensive thing made avaible for free and open-soruce, and i love it i'd say we both finish our filters and their documentation (this time i'll write one, really, i think...) and then we see if we can combine features Last edited by E-Male; 20th July 2005 at 18:23. |
