The image resolution can be improved without increasing the requirement to optical imaging systems' parameters and decreasing the size of CCD pixel by staggered arrays technology
which arranges several CCDs in a specific mode. In this paper
an image super resolution method of improving the image resolution for 1.5 times both in two directions by 4 linear arrays staggered based on this technology is presented
which avoids the large computation in a single time by use of circulation method. This method is proved effective by the digital simulation
and a simulated experiment platform is constructed to test its feasibility. The image resolution is improved for 1.42 times of the unreconstructed image according to the imaging experiment of resolution chart
which is closed to 1.5 times in ideal case. And also
the reconstructed and unreconstructed images are evaluated by the image information entropy
which proves that the reconstructed image contains more information. 2011 IEEE.

In order to carries on the plan and the control to aircraft level flight
then obtain that the factors control the level route are the route position and the radius of turn
finally carries on the software simulation using this algorithm
the attitude and the route has been analyzed. First obtain that the factors control the level attitude are the roll angle and the yaw angle
and infers the algorithm of flight route
according to the attitude and the route restraint
and infers the computation algorithm of attitude
produce shortest aircraft level flight road map which through the giving route position on the software surface. According to this algorithm
it may control and plan the aircraft level flight
through to limit of the aircraft security attitude and the route position. 2010 IEEE.

RS code is a linear error correction codes with better error correction capability
is widely used in different kinds of occasions for communications or data storage. But for its high difficulty of coding and decoding algorithm and low throughput
optimization RS algorithm is always studied as one of the focus in the error-correction field. A new coding method
parallel coding and decoding data into groups in lower step finite field for avoiding complex matrix iteration and Chien search computation
is proposed in this paper. It is proved that the coding and decoding throughput of the parallel grouping RS coder is increased and the hardware complexity is reduced with changeless error-correction capability from the simulation results using ModelSim SE 6.0 and synthetic results using ISE 9.11. 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.

In order to obtain three-dimensional observation effect with single satellite borne time delay and integrate charge coupled device (TDI-CCD)
pitching imaging is required. More accurate real-time image motion velocity vector computational model of space camera is also necessary to make the imaging perfect. Imaging motion velocity vector computation model must be set up on image plane at pitching imaging. According to the geometric relationship between the pitching imaging space camera and the Earth's rotation motion
satellite borne TDI CCD pitching imaging motion velocity vector model is derived by mapping the ground speed to the image plane and using coordinate transformation method. The numerical simulation results show that the image velocity model can reduce deviation angle error about 33' and about 30% image motion speed error compared to traditional ground velocity model. 2009 IEEE.

Image segmentation is the first essential and important step of low level vision. This paper proposes a novel algorithm for adaptive image segmentation
it can be applied in many conditions
based on thresholding technique and segments merging according to their characteristics combine with spatial position. Our earlier work of getting the entire information of the histogram could help choose the multiple thresholds. However
including complex target segmented. We describe the algorithm in detail and perform simulation experiments. The computation based on pixels can fully parallel processing to save time. 2006 IEEE.
not all the peaks of the histogram correspond to obvious structural unit in the image. Spatial information must be involved. This paper also suggests subjoining segments matching for video image tracking. They will give great help to image segmentation. The proposed algorithm can meet the real-time requirement and lead to higher segmentation accuracy
some types of texture can also be segmented well
