Wavelet transform coding has been drawing much attention because of its ability to decompose images into a hierarchical structure that is suitable for adaptive processing in the transform domain. This paper presents an E$cient VLSI design of one-dimensional direct discrete wavelet transform processor. The proposed architecture computes three DWT stages and(More)
The automatic detection of road signs is an application that alerts the vehicle’s driver of the presence of signals and invites him to react on time in the aim to avoid potential traffic accidents. This application can thus improve the road safety of persons and vehicles traveling in the road. Several techniques and algorithms allowing automatic detection(More)
