Appropriate Level of Detail

[Tervuren]

My work heavily involves creating simulated results.
The lower the level of detail, the faster I can obtain a result.
However, lower levels of detail can hide critical flaws.

Lets look at different levels of detail as pictures.
Here is what it is like to compare two different countries at a country level.
The first seems to be grey while the second seems to be brown.
Country 1


Country 2





This is what it is like to break down those countries into six regions each.
Suddenly the second country seems to have some very dark grey that we didn't know was there.
Country 1


Country 2




This is what it would look like with each country divided into 54 segments.
This would be comparable to looking at the United States on a state by state level.

Country 1


Country 2


A this level:
Country 1 has some greenery, and perhaps some lakelands.
Country 2 Looks like it is mostly desert wasteland.

At this level, there are still critical observations being missed.
Within each of these divides exist yet more divides.
Very few people have a world view that exceeds this level.
What is critical can be missed entirely.

Here is a level of detail similar to a county by county view of the US.





















Country 1


Country 2


At this level of detail one should be able to make out that these weren't pictures of countries but pictures of cars.
Until this level of detail is reached it is easy to be misled.
At this level of detail if one knows their cars they can identify the cars.
Although one might still be a weak fake and it'd be hard to tell.

Are you pixellating images of Ferrari's and Lamborghini's on your time or your employers time?

I'm seeing a cartoon dog with a geisha hairdoo and huge mustache.
Shirly you're mistaken.

I think I get where you were going with this.

It's not just about the level of detail, it's about whether or not people consider the detail.

Too many would look John's duck pic and discard everything but this.

I thought nude pictures were banned. Hope Zman doesn't see that.

Too easy, Country 1 is the UK in the winter or Beijing in the summer

Country 2 is a little more difficult somewhere in the Middle East during a sand storm

Here is a picture of the country I lived in



Here is a picture of the country where I had one of my favourite holidays, had a really good camera with me so the focus is a little sharper

I'm still waiting for the point or punchline.

Pics from Facebook?

The answer is mu. (i think)

Stomach Monkey, you've reminded me that I left out appriorate level of scope as also being a problem.

Where I'm going with this:

1. Not finding important differences that can only appear as level of detail is increased.

2. The source data is not accurate at suffecient detail level.
Increasing the level of detail beyond the level of data would only result in unreliable pixels.
One cannot get an accurate picture without additional levels of detail in the data.

3. The problem of scope is looking at a single pixel or small group of pixels and judging the rest of the image unseen.
Racists would be people trapped in this problematic microscopic worldview.


The level of detail, the scope of the search, each of these must be appropriate to find an accurate result.
A good way to find the appriorate level is to increase scope or detail and see if the same findings remain.

The pixels one has control over should occupy one's decision making power rather than pixels where one's control is lacking.


On top of scope and detail there is also perspective.
