Abstract

Due to the existing image definition evaluation functions in auto-focus systems easily affected by noise, an image definition evaluation algorithm based on lifting scheme is proposed. The algorithm uses lifting scheme for wavelet decomposition, and adopts the energy value of high frequency components of wavelet decomposition as image definition evaluation function. Theoretical analysis and extensive simulation results show that this method, compared with other image definition evaluation functions, has higher sensitivity, excellent anti-noise performance, low computation burden and high reliability, so it can better meet the requirements of image definition evaluation.
