An adaptive differential evolution algorithm with novel mutation and crossover strategies for global numerical optimization by Suganthan, P. N., Ghosh, Saurav, Roy, Subhrajit, Islam, Sk. Minhazul, Das, Swagatam

“…A DE variant obtained by integrating the proposed mutation, crossover, and parameter adaptation strategies with the classical DE framework (developed in 1995) is compared with two classical and four state-of-the-art adaptive DE variants over 25 standard numerical benchmarks taken from the IEEE Congress on Evolutionary Computation 2005 competition and special session on real parameter optimization. …”

Accurate two-stage frequency offset estimation for coherent optical systems by Huang, Dezhao, Cheng, Tee Hiang, Yu, Changyuan

“…Simulations show that the mean square error of the proposed FOE can be reduced through an order of two in magnitude under small laser linewidth situation compared with the classic phase-difference-based FOE. The experimental result shows that the proposed FOE gives 0.6-dB optical-signal-to-noise-ratio improvement against the classic FOE, which validates its usefulness.…”

An affine invariant feature detection method based on SIFT and MSER by Wang, Zhuping, Mo, Huiyu, Wang, Han, Wang, Danwei

“…In this paper, an affine invariance feature detection method based on Scale Invariant Feature Transform (SIFT) and Maximally Stable Extremal Regions (MSER) is proposed. Classical SIFT algorithm is not robust to affine deformations, because it is based on DOG detector which extracts circle regions for keypoint location. …”
