A optimum algorithm based on gradient sharpening about edge detection of image is proposed according to the shortcoming of the conventional algorithm unable to recognize the blurred edge,unclear character in the image of instrument on board.

We put forward a new algorithm to detect the Center of Structured Light Stripe combining gradient sharpening with barycenter method,which firstly extracts fringe using gradient sharpening,secondly gets .

In this paper a new algorithm is presented based on the outer outline of the human s image in the photo,which includes gradient sharpening,edge protection and comparing the similarity with the pixels nearby.

Object detection method based on morphological opening-and-closing operation and gradient optimization

The gradient optimization algorithm based on the stochastic finite element was adopted to analyze the reliability of the frame with stochastic parameters.

Preliminary analysis of the near-ground gradient changes of air relative humidity on grazing meadow of the Qilian Mountains;

The structure of plant communities and gradient change of species diversity in typical district(Feihong Bridge in Mao County) of the upper reach of Minjiang River were studied.

Add the term of self-polarization-gradient to the equation of Ginzburg-Landau, this paper has studied the hysteresis loop of ferroelectric bilayers, and adopted the average polarization to reflect the character of the bilayers.
