Parallel recognition and classification of objects
Felice, Rodrigo - Ruscitti, Fernando - Naiouf, Marcelo - De Giusti, Armando Eduardo

Formato:	Articulo, Articulo
Enlaces:	The development of parallel algorithms for an automatic recognition and classification of objects from an industrial line (either production or packaging) is presented. This kind of problem introduces a temporal restriction on images processing, a parallel resolution being therefore required.…

Application of symmetric orthogonal multiwavelets and prefilter technique for image compression
Chen, Jiazhong - Zhou, Jingli - Yu, Shengsheng - Xiao, Qian - Xu, Jun

Formato:	Articulo, Articulo
Enlaces:	Multiwavelets are new addition to the body of wavelet theory. There are many types of symmetric multiwavelets such as Geronimo-Hardin-Massopust (GHM) and Chui-Lian (CL) multiwavelets. However, the matrix filter generating the GHM system multiwavelets does not satisfy the symmetric property.…
