The filter,which combines the properties of Gaussian filter and Gradient Inverse Weighting Filter,takes simultaneously the space distance and pixel distance into account,so as to choose the pixels and their weights for local smoothing.

Research of image separation based on improved independent component analysis;

Study on Speech Separation and Image Separation Based on FastICA

The method of wavelet threshold de noising and the algorithm of Fast ICA are studied with the simulation of noisy mixed image separation.

Quick algorithm for fractional-pixel accurate motion estimation;

The quality of reconstructed images can be enhanced by a temporal error concealment algorithm based on a fractional-pixel boundary-matching search for the newest international video coding standard H.

Different from conventional quarter-pixel accuracy hierarchical motion estimation algorithm,the proposed algorithm can avoid fractional-pixel interpolation and subsequent fractional-pixel search after integer-pixel accuracy motion estimation.

This paper uses high resolution area CCD,provides a new lighting method of scattering and uniformity,through edge detection and pixel subdivision technique,raises the accuracy of measurement that is usually limited in one pixel to 0.

The edge detection and pixel subdivision are the indispensable steps of the graphical measurement.
