MP3 (LAME Encoder)

MP3 (Xing Encoder)

An algorithm predicts the next sample based on the previous samples, and the encoder stores only the difference between this prediction and the actual value.

And so the encoder does just what I was saying it mimics the actions of the front end circuitry so it takes images in and converts them into the retina's code.

Okay, so I just want to take a sentence or two to say something about the encoder and what it's doing, because it's really the key part and it's sort of interesting and kind of cool.

Here are three sets of firing patterns. The top one is from a normal animal, the middle one is from a blind animal that's been treated with this encoder transducer device, and the bottom one is from a blind animal treated with a standard prosthetic.

So as you can see, the firing patterns from the blind animal treated with the encoder transducer really do very closely match the normal firing patterns and it's not perfect, but it's pretty good and the blind animal treated with the standard prosthetic, the responses really don't.
