Abstract: Image processing has been widely applied in various fields. Photoshop image processing software is the best one for the enthusiasts. At present, more and more people are interested in using Photoshop to create some characteristic pictures, while the key and difficulty part of image processing in Photoshop is matting method (create the image area).In order to help the image processing enthusiasts to accomplish in the process of image processing and create a more beautiful image, this paper introduces several commonly used matting methods in Photoshop and discusses in detail the scope of application, the using methods, the advantages and disadvantages of them.

Abstract: Genetic algorithm is a search algorithm based on genetic mechanism and natural selection. It has been widely applied to research fields including image processing field. The paper improves standard genetic algorithm and improves the arithmetic speed of the algorithm, which achieves better image restoration effect. And the paper compares the image restoration quality of traditional algorithm, standard genetic algorithm and improved genetic algorithm to prove the feasibility of applying genetic algorithm to image restoration.

Abstract: In this paper, the advantages and disadvantages of the existing ultrasonic image management system are analyzed, and also a multi-functional color Doppler ultrasound image-text management system is researched and developed in combination with the experience of color Doppler ultrasound doctors. With this system, the related operations such as color Doppler ultrasound images acquisition, processing, preservation, and medical records are implemented. In the design of the system, a professional acquisition card is used for implementing the acquisition of ordinary video signals. In the meantime, DICOM interface is designed using DICOM3.0 protocol for implementing multi-mode acquisition.

Abstract: According to the unmanned aerial vehicles real-time video image acquiring and target detection requirements, an image processing system was designed based on FPGA and TVP5150A decoder, and the video decoding hardware and software was also designed to meet the demands of unmanned aerial vehicles. An I²C controller was realized to assure the implementation of video decoding process in accordance with the requirements, and an image processing algorithm and applied to the image recognition process. Both of these were completed in FPGA using verilog HDL language. The correction of this image processing system was verified through real-time experiments.

Abstract: Optical microscopy presents an extension of standard methods for pore space description. In this paper two examples of application in materials and mechanical engineering are introduced. The porosity and pore size distribution of two types of AAC are measured. In the second example the thermally induced cracks of cement fiber composite are visually detected and mathematically described. The technology of sample preparation, measurement technique and digital image processing is described, while advantages and disadvantages are discussed.

Abstract: To conveniently find parking spaces for college staffs and visitors, the university parking query system is designed based on C/S architecture. By the design of automatically obtaining parking information based on image processing technology and the design of parking information inquiry, the system enables parking information exchange between Android mobile devices and Web server. It could improve the efficiency of parking spaces and also reduce the time spending on finding parking space.

Abstract: A novel edge detection method based on anisotropic mathematical morphology and scale multiplication in nonsubsampled contourlet transform (NSCT) domain is proposed to obtain a superior and robust performance under heavy noise. One preliminary result is obtained using anisotropic morphological gradient of the low-frequency component, yielding a single-pixel response with few pseudo edges. Due to the great ability of NSCT to localize distributed discontinuities such as edges, scale multiplication results of high-frequency components can get rid of a large amount of noise and produce well-localized edge candidates. The final result is a fusion of the detection results of low-frequency component and high-frequency components. Detailed experiments compared with other state-of-the-art methods demonstrate that the proposed method has a superior performance of edge detection and is quite robust even under heavy noise.

Abstract: The full-wave band CCD system is widely used for military,civil or photography of criminal image and extraction analysis,its wavelength is range between 200 nm and 1200 nm,including ultraviolet,visible light and infrared.Through translating blanck visibleimage into optical image,and realizing collecting of weak signal under low illumination case and collecting and processing of high quality image,it makes Full-wavelength CCD system the powerful features such as the topography and landform scaning,traces exploration,file inspection,holographic photography and image processing.The whole band CCD system structure,characteristic and the application of the image interpretation technology were briefly introduced in this paper,and experiment band CCD selected was validated.
