| GeneralStupid | i think i want to do an motion detection on the openrisc and on openrisc with special co processors... i just want to detect moving things. I think its very easy, pictute_(i-1) - picture(i) = moving thing (ok, needs some filtering...) | 07:28 |
|---|---|---|
| olofk | GeneralStupid: Just do it! :) | 07:31 |
| GeneralStupid | wouldnt it easier to use a DFT on both pictures and delta them and use inverted DFT on the result? | 07:34 |
| stekern | GeneralStupid: we had a project in the last year of university that implemented motion detection in an fpga | 15:35 |
| stekern | s/had/did | 15:35 |
| stekern | the way we implemented it was really simple, we divided the screen into blocks and recorded the average of the pixels in each block | 15:39 |
| stekern | and then compared the previous block array with the current frame | 15:39 |
| stekern | we had to do it that way because we were memory constrained, but it actually worked fairly well | 15:40 |
| olofk | stekern: Got any keys signed lately? | 21:50 |
