It is introduced a novel imaging technique for medical diagnostic X-ray coherent scatter in this paper. A set of experimental equipment for X-ray coherent scatter imaging was set up with X-ray digital flat detector and medical diagnostic X-ray source. According to this equipment
the scatter images obtained are made of some circles with the same center. It is vital to calculate the energy template to classify the different samples. It is difficult to separate them using the traditional threshold method due to noise and overlapped shadow. In this paper
the image was transformed a binary image by using K-Means algorithm and Mathematical Morphology Methods. The effective region was extracted from the binary image inside the orthogonal energy projection space
then to calculate the centroid of rings. Consequently the curve of the energy distribution was built. The experiment results show that our method is reasonable and feasible. The technique will have wide foreground of application .Besides the imaging of human bone content
it can be used for various imaging of tissue and organs in biology. 2010 IEEE.

In order to improve the accuracy of license plate character segmentation
use line-shape filter to remove plate frames. Then character segmentation approach combines projection and inherent characteristics of character
this paper strengthens preprocessings before segmentation. In character binarization
can better solve character adhesion and fracture problem. For tilted characters only in horizontal direction
use improved Bemsen method to reduce noise interference
even without tilt correction
this method can achieve better segmentation. Experiment results shows the accuarcy of character segmentation reaches 97%. 2010 IEEE.

Subspace based methods have been widely discussed in multichannel estimation including MIMO-OFDM system. However
direct subspace methods suffer from heavy computation complexity y of O(N3). In this paper
a new subspace tracking technique called Fast Data Projection Method (FDPM) is proposed for adaptively tracking the noise subspace. The new algorithm has low complexity of O(NL) and is the only numerically stable
low complexity algorithm for tracking subspaces corresponding to the smallest singular values. Simulation results show that the proposed scheme has similar performance to the original. 2009 IEEE.
