[libdmtx-open_discussion] Are there any reference papers for libdmtx?

[Tsang W. <hu...@gm...>]

I'm trying to porting libdmtx to embedded ARM.But for some pictures it's
slow for libdmtx to recognize the barcode.I noticed that libdmtx locates
barcode base on hough transform,which is time-consuming for embedded
systems.I'm trying to modify it with some alternative algorithms such as
convex hull algorithm or differenciation algorithm.But I do not know what is
 the grid scanning algorithm for libdmtx.Are there some reference papers for
libdmtx?
Thanks.
