Image mosaic is an important branch in the field of image processing. This paper designs and realizes an image mosaic technique based on the information of edge. The technology is suitable for engineering application. First of all two images of the adjoining frames are processed by convolution operation get the edge images. And then we cut edge image into pieces and compute their spatial frequency. According to the value of the spatial frequency select reasonable registration model group. We compute correlation strength and the value of movement offset which are the model group and the current frame edge image. We can complete image mosaic by them. We use video sequence which of the resolution is 1024 * 768 do the experiment. The results show that the method has good effect and strong adaptability. Algorithm is high efficiency which running time is 24 ms. It is suitable for real-time processing requirements of the application. This method is an effective mosaic technique which is suitable for engineering application. 2012 IEEE.

Weak stars and middle altitude orbit satellites or high altitude orbit satellites are presented as dim point targets in images of astronomical observation. They have low intensity and occupy few pixels in image. In most situations the background of sky is always ununiform and there exists pulse noises. Thus results in targets submerging in background noises and low signal noise ratio (SNR). Median filter is an effective method for removing pulse noise. But it can blur image after modifying gray of non-noise pixels when image has low SNR. A hybrid median filter algorithm is proposed to process low SNR dim point targets image. The newly proposed method can suppress the pulse noises also can increase target $SNR$ and does not add extra fake targets. The time complexity of median filter is O(N2)(N is the widow size) and is difficult to implement in hardware. For quasi real time application a fast implementation of our hybrid median filter is proposed to reduce the time complexity to O(N). Experimental results show that the newly proposed algorithm is superior to ordinary median filter and fast median filter by comparing visual effect and performance. 2011 IEEE.

In order to satisfy requirements of real time and parallel control for the space optical remote sensor and implement the high integration of software a kind of VxWorks-based multitask software architecture was put forward. Firstly the technological requirements of optical remote sensor were analyzed in detail and functions and performances of the optical remote sensor were fixed. Task that was based on each function of optical remote sensor was compartmentalized. Then software architecture of optical remote sensor was designed. Finally experiments were carried out and results verified the accuracy and feasibility of the software architecture. Test results showed that the software architecture satisfied the requirements of real time and parallel control for the space optical remote sensor its functions and performances met the system design target perfectly and the software architecture was applicable to the engineering application of space instrument. 2011 IEEE.

The common bus on bus control is RS232. With the development of field bus technology field bus technology is widely used in data recorder. How to real time record the data of field bus in the experiment and provide the test data for process reconstruction is a very important problem. This paper introduces a kind of data acquisition and storage based on field bus. Its core design is C8051F040 microprocessor and SJA1000 a widely used field bus controller. This paper presents the basic constitution of this field bus data recorder and set forth its hardware and software. This field bus data recorder field bus real-time gathers the information and storage data on the CF card. The result of the experiment shows the system is highly reliable for data acquisition and storage which should have abroad application prospect for data record experiment. 2010 IEEE.
