In this paper we introduce the new integrated color and texture based image retrieval technique using neuro-fuzzy approach for content based image retrieval. Most of the image retrieval systems are still incapable of providing retrieval result with high retrieval accuracy and less computational complexity. To address this problem, we developed color and(More)
In communication, convolution codes are extensively used for reliable data communication at receiver's end the coded messages are decoded with Viterbi Decoders. However when the channel is noisy decoding becomes computationally complex even with enhanced Viterbi Decoder, hence it necessitates an efficient computationally less complex decoders. In this paper(More)
Convolution coding is the most commonly used channel encoding technique for reliable data transmission. At the receiver's end, Viterbi decoder is used for extracting the message bits. Though these decoders can correct any number of errors, complexity of the decoder increases with the number of bit errors. Hence research began in this area, to design(More)
Convolutional coding is the most commonly used channel encoding technique for reliable data transmission. While using convolutional coding Viterbi decoder is used to decode the data at the receiver end. As decoders can correct the n number of bit errors, when number of bit error increases the complexity of decoder also increases. So researchers have started(More)
In VLSI circuit power reduction is of major concern. Considerable research is carried out in literature to develop techniques to reduce both dynamic power and leakage power. However attempts are still in progress to reduce the power without degrading the performance of the circuit in terms of speed and accuracy. In this paper a novel DML approach is adopted(More)
CDFG plays the most important role in digital circuit design as it directly affects the area, speed and cost of the designed circuit. Hence in order to obtain an effective circuit, it is necessary to optimize CDFG. In this paper a detailed study on CDFGs for four different circuits is made for both pipelined and non-pipelined architecture. Performance is(More)
