An image quality assessment model based on gradient complex matrix is proposed. The vertical and horizontal gradient information of grayscale image is calculated. Complex number is used to construct the measuring matrix. Singular value decomposition is performed in order to obtain the main structure information of the image. The singular value feature vectors of the image gradient complex matrices corresponding to the reference image and the distorted image are used to measure the structural similarity of the two images. PSNR is taken as a tool to evaluate the gradient distribution similarity. Their properties are analyzed by using LIVE database and nonlinearity regression function. 2012 IEEE.

The target classifier is an ingredient of the target recognition system. In order to achieve the automation and computerization of target recognition a method for training target classifier based on semi-supervised learning is provided. It adopts CFS algorithm for dada feature selection and uses semi-supervised learning algorithm Co-training to construct the target classifiers. The final classifier was produced through integration learning method. Experimental results show that the performance of the target classifier based on semi-supervised learning trained is superior to the traditional target classifier. 2011 IEEE.

The applications based on traditional digital cameras have been limited by distance cost and networking. Gigabit Ethernet is a data transmission standard based on the IEEE 802.3 protocol brings several benefits to image transmission. In this paper we compare the main features of Gigabit Ethernet and traditional digital camera interfaces. And we design a high speed image acquisition system which overcomes these application limitations by allowing cameras to send imaging data over Gigabit Ethernet. In this system we design a highly efficient bidirectional conversion device based on FPGA converts imaging data from a camera to IP packets based on UDP protocol and sends it to PCs over inexpensive Cat-5 copper LAN cable. At the PC the Cat-5 cable plugs into a standard Gigabit Ethernet NIC(network interface card) eliminating the need for a frame grabber. An communications application software is used to acquire the network data construct and display the image. A simple and efficient acknowledge and resend mechanism was used to guarantee packet delivery. The system architecture and the communication protocol are discussed in details the experiment and results are presented in this paper. 2010 IEEE.

Based on reflective liquid crystal spatial light modulator (SLM) a new foveated optical imaging system is proposed. High quality imaging can be realized at any region of interest (ROI) within the field-of-view (FOV) by utilizing the SLM to correct the aberration of different regions dynamically. A reflective cassegrain optical structure is proposed which is designed optimized and matched with the reflective SLM to construct a more practical foveated imaging system. This reflective imaging system has a large aperture so that enough light can reach the image plane. It also makes the total length of the system shorter and therefore more practical. We also simulate and analyze the system. This kind of foveated optical imaging system can be applied in wide FOV imaging aspects to reduce bandwidth and optics complexity and to achieve weight reduction and miniaturization. 2010 Copyright SPIE - The International Society for Optical Engineering.

We present a computationally efficient color image fusion algorithm for merging infrared and visible images. At the core of the proposed method is the color transfer technique based on the linear YCBCR space. The method directly uses the grayscale fused image and the difference signals of the input images to construct the source YCBCR components then uses the statistical color transfer technique to form a color fused image that takes the target image's color characteristics. Two different strategies which respectively employ the pixel averaging fusion scheme and the multiresolution fusion scheme as the grayscale image fusion solution are proposed to fulfill different user needs. The simple strategy using the pixel averaging fusion scheme answers to a need of easy implementation and speed of use. And the complex strategy using the multiresolution fusion scheme answers to the high quality need of the fused products. In addition we also describe some useful theories about color-transfer-based image fusion. Experimental results show that the proposed color image fusion algorithm can effectively produce a natural appearing "daytime-like" color fused image and even using the pixel averaging fusion scheme to implement the grayscale fusion can also provide a pleasing result. 2010 Copyright SPIE - The International Society for Optical Engineering.

The real color video consumes much transfer bandwidth and the resource of the hardware. A new approach is introduced to process the real color video images in real-time using color components combination to fit to the limited transmission bandwidth. The Y U V planes of video images are packed to construct a 2 dimensional complex array. Through the decomposition of frequency domain the Y U V frequency can be got respectively by performing Fourier transform a time on the specific complex array. These frequencies can be filtered to generate the final filtered images. The experiment results show that the proposed algorithm is 3X speed compared to the traditional algorithm and it reduces 1/3 bandwidth of video data stream. 2010 IEEE.
