perspective correction?
« on: Feb 3rd, 2005, 11:24am » |

Has anyone implemented some perspective correction algorithm in Processing?
I am trying to implement a rudimentary custom barcode-system. When the user takes a photo of the coded mark (lets assume a conventional b/w pixelated barcode), the perspective of the image is corrected to be aligned along the x/y axis. Next each cell in the grid is tested for b/w value etc.
For now I would like to concentrate only on finding the 4 corners of the mark and correcting its perspective so that I get consistent images which can be further interpreted.
I am an intermediate programmer. Don't know too much about matrix algebra. Any hints?
