Subject: Uploading technology (1.i.1)

Uploading technology (1.i.1).
 
A uploading project must include four elements: 
- A molecular scale scanner.
- An image processing software able to extract informations from the scanner 
data.
- An electronics brain simulator.
- An interface system to link the brain and the world.
 
I am mostly concernet here with the third element, but the other must not be 
neglected. For example the interface system must include the sensory inputs 
and a robot body. The picture processor must be able to see the dendrite 
elements, sort them out from glial cells, look at significant element such 

cytoskeleton molecules in dendrite spines, deduce the presence of a spine from 
decay 

products of channel receptors and so on. These products may have migrated 
because 
of both, the brownian motion and a nearby ice crystal formation for example. 
The main work would be done by a computer, but some image cleaning may be 
worked out by a neural network.
 
Producing such a neural net and integrating into a computer could be an 

interesting intermediate step before looking at a full scale brain size 
electronics 
processor.
 
I must say that I am not a specialist in computer picture processing, but 

I'll try to get some basic understanding of the technology. The two elements to
look at are, it seems, the 3D picture using voxel (volume element), not pixel 
(picture element) and a block element of the neural net using a single FPGA. 
This elementary system would include all or nearly so what would be found in a 
brain quality neural net. There would be the time sharing capability, the 
memory on dendrite tree, the slow process on computer and so on.
 
Producing these systems will cost a lot of money, so there must be too some 
intermediate market products. For exemple to recognize a partly hidden or 

destroyed object asks for some understanding of what is seen. In the same way, 
to 

translate speech from one language to another implies some background knowledge
of the world, the society and so on. The basic problems are not very 

different. May be a real time translator would be a better market choice than 
the 3D 
picture interpreter...
 
In the same way, working with voxels may be hard at first. It could be 

simpler ti use 2D pictures taken in different plane. The scanner itself can 
produce 
its output in this form.
