Image enhancement based on lifting wavelet transform

2009 4th International Conference on Computer Science & Education, 2009
The traditional image enhancement algorithms enhance noise signal in image while they enhance image, which leads to the de-scent of information entropy. Designing image enhancement systems with good nature is a goal which all researchers pursue. Method of lifting can best deal with MRA Multi-resolution Analysis method which is time and memory consuming

Lift enhancement study and experimental verification for ornithopter

Engineering Research Express
Abstract Ornithopter is a research hotspot of unmanned aerial vehicles. In this paper, an ornithopter inspired by birds is designed. The fin deflection mechanism is adopted. During the upstroke phase, the fins are passively unfolded to reduce the resistance when the wing moves upward; while during the downstroke phase, the wings are ...
