A Low-Power VLSI Implementation for Efficient Removal of Impulse Noise using CLA
نویسنده
چکیده
The impulse noise is caused by sharp, sudden disturbances in the image signal. Its appearance is randomly scattered white or black (or both) pixels over the image. In this paper, an efficient VLSI implementation for removing impulse noise using CLA is presented. Our result preserves the edge features and obtains excellent performances in terms of quantitative evaluation and visual quality The design reduce the low complexity impulse noise with low cost of hardware implementation. Compared with ripple carry adder, CLA(carry look-ahead adder) achieves a better performance and reduced carry propagation time. Here Xilinx power estimator(XPE) is used to compare the power required for VLSI implementation.
