Anon, human minimal viable population is 5000, are you implying that nowhere on earth there will be a village with 5000 people left?

Hey /sci/, figured I'd come to you for help on this one. I'm doing research with a few professors at our university, and we're trying to find a good method in MATLAB for a certain operation.

This is what we're trying to do:

We have a ton of .jpg and .bmp files that are being read, pixel by pixel, on a brightness scale of 0 to 1 in order to be put into a Genetic Algorithm and transformed into a new image.

What we're exploring is, instead of doing this pixel by pixel, doing it by throwing x number of random polygons onto the image and mapping it with those.

This is similar to a project that was done a few years ago where the image of the Mona Lisa was taken and replicated by a genetic algorithm with polygons. A good link to check out is:

http://rogeralsing.com/2008/12/09/genetic-programming-mona-lisa-faq/

However, in the above example his fitness function remains relatively simple and does not deal in polygons. We want out fitness function to create a random number of polygons in order to create this new image instead of having to read it pixel by pixel (because at the moment, 22,500 elements is not a fun thing to deal with).

This is probably a little devoid of information and lacking specifics, but a lot of this is over my head.

I've been looking through the MATLAB help files to try and find some kind of polygonal method similar to this, or some other kind of help (my prof. told me to do this, not much luck so far).

Any ideas or suggestions? I'll try and supply whatever other information I can.

>that feel when 80% chance of developing cancer due to a gene, 50% chance of passing the gene on

So hows gene therapy technology coming along? That one fucker is spoiling the mix. My chance of dying from it is already lower than the average due to regular screening... but still.

Are any of you ACTUAL engineers or scientists?

Students don't count. I feel like I'm surrounded by ignorant kids here...

The y component of the point charge is located at x = 0.190, y = -0.350m

Electric field question here. There is a negative charge of -9.00nC at x1 = -0.190m. There is a positive charge of 9.00nC at x2 = 0.190m. What is the electrical field at point x = 0.380m. On all of these points, y = 0. The main formula is E = k( |q|/ r^2).

I first thought that since the forces were attracted to each other, I would subtract them to get the net charge at the given point. This however was wrong, and I needed to add both of these charges together to get the magnitude.

My question is, why would I add the charges together to get the overall magnitude, if the positive and negative force would be attracted to each other?

But there are no mods. I've seen a gay porn thread reach image limit, and nothing done about it.
