—Reconfigurable Optical Add/Drop Multiplexers (ROADMs) manufactured with different designs and technologies are soon going to be available in the market. Unfortunately, the latest available ROADM architectures are either suffering from high insertion losses or high manufacturing costs that prevent their rapid deployment in the network. In this paper, we(More)
Vector Quantization is one of the most powerful techniques used for speech and image compression at medium to low bit rates. Frequency Sensitive Competitive Learning algorithm (FSCL) is particularly effective for adaptive vector quantization in image compression systems. This paper presents a compression scheme for grayscale still images, by using this FSCL(More)
