By analyzing the thought of basic genetic algorithm in solving the Traveler s Sale Problem,roulette wheel selection is also chosen;crossover method is a the heuristic method of crossover algorithm,the crossover location is random,this algorithm generates a better answer by fixed chances,the chance of crossover is 0.

A Cross Entropy Algorithm for Maximum Clique Problem and on It s Parallelization Study;

Edge detection of CO_2 arc welding pool image based Bubble wavelet and zero crossing;

Wavelet zero crossing representation is investigated.

Based on zero crossing representation of wavelet transform of this radial function and matching procedure, a new algorithm to identify orbits of shaft centerline is proposed.

For the first frame of the video, the object edge is obtained by an enhanced interactive method; in the remaining frames of the video, a new Snake algorithm is proposed to detect the sharp-angled and concave object contour under the constraint of zero-crossing point, the experimental results of different.

The traditional method which uses a threshold to every zero-crossing points to detect salient edges by LOG operator,can filter parts of unconspicuous edges caused by noise,but it can also filter the weak edges connecting to salient edges.

An Improved Approach of Image Edge Detection Based on Zero-crossing;

The background noise is considered as a series of impulse and analyzed by zero-crossing method.

The methodology is based on zero-crossing algorithm, with feature point detection algorithm added to improve detecting accuracy and speed on the zero-crossing method.
