Weekly Theme: My daughter & texture marquetry

[Michael Gerald-Yamasaki]

Folks,

Greetings. This one will take a little explaining...



A quick candid while birding got me this blur (1/13th sec at 600mm HH ;-) and the amused at silly Papa look that makes me smile. The texture is a data visualization technique I developed for analyzing fluid flow data applied here to the image data. The technique places a small texture of oriented flow lines in the direction of the fluid flow (a technique I call vector field marquetry). Here I used the brightness value in the image to guide placement of the oriented texture patches. As such the "flow lines" texture conforms to the image content. A little experiment for the theme applying this technique to photographic image data.

The texture was soft light blended with the original with a reduced texture blended with the face and neck.

Thanks for looking.

Cheers,

-Michael-

Nice!! And a beautiful subject!! Looks like she manages to tolerate you well!

[Cheryl Slechta]

Hi, Michael, whatever you did is way too technical for me but I'm enchanted by the result.

[Judy Howle]

I'm with you Cheryl, but it is a very unique and interesting texture applied to a very pretty subject! I like the results.

[Christopher Miller]

Cool! Very unique technique, Michael. I love the fine detail of the texture. I might mask the effect off the eyes more. Very nice work!

[Dennis Bishop]

This definitely deserves points for breaking new ground in photographic processing. I like what you've done, but I agree with Christopher about the masking (perhaps more than just her eyes?).

I'm guessing your fluid flow visualization technique is applied to the output of mathematical modeling, yes?

Diane, Cheryl, Judy, Christopher, Dennis,

Thanks much for your comments. They are much appreciated. Some of the issue for me with the eyes is from the motion blur & am planning some work there. The original technique was indeed used on numerical simulations, Dennis, but I've also applied it to sensor data, well, as it has been applied here ;-) but also other types of sensor data. There's more to come with this technique... I'm anxious with ideas on application to photographic processing. It's that simple matter of programming.

Cheers,

The bkgd you mathematically created is fascinating! I love how it also engages her hair. Agree with having a less blurred face, but I did notice your speed was only 1/13th!

[Jackie Schuknecht]

Can't say I understand it either, but it is a beautiful result! It is almost like a topographical weather map. (The BG).

[Michael Gerald-Yamasaki]

Nancy, Jackie,

Thanks much for your comments. Jackie, I have used this technique to make topo maps ;-).

All,

So.... this might be a better explanation of what I'm doing (if you are interested):

The original image (top left) is posterized by brightness (bottom left). 4 poster levels.
Each poster level is replaced by different oriented textures, I messed up on the tiles at the bottom (sigh) but you can see different orientations of the texture and how it is applied to each poster level in the bottom right image.
Top left shows partially blended texture with original.
The OP uses 32 levels and 32 oriented textures in this manner.


Hope this makes sense. The original application of this method is for flow visualization. The "posterization" is guided by the flow direction as determined by the flow data, so the oriented textures are placed as the direction of flow.

For this BPN image, the technique uses the image brightness to guide how the texture is applied. I'm working on other ideas with respect to "content-aware" texturing of images for grins.

Thanks for looking.

Cheers,

-Michael-

[Dennis Bishop]

Many thanks for taking the time to explain this further. I'll be interested to see what you come up with next.

[Diane Miller]

Very impressive! Let us know when you have the app done, so we can hopefully use it without having to understand it!!

A pleasing composition, with her hair flowing to the left. I like her expression, half smile on lips and eyes. An unusual and attractive processing technique. Congratulations on your creativity. I'd like to see a bit more clarity in her eyes. lovely daughter and work.
