To overcome the degraded images taken in hazy weather, an adaptive restoration method based on improved contrast enhanced restoration was proposed. Firstly, by quadtree subdivision searching method, the sky area of multichannel polarization image are extracted automatically, and the atmospheric light and degree of polarization are calculated;Second, scene depth information of image are calculated based on contrast enhancement method. Then, atmospheric intensity are thinly restored by guided filter, finally the degradation image are restored. Experimental results have shown that the proposed method can improve fog degradation image and increase definition of the image effectively.

Infrared polarization imaging detection can be used to obtain not only the polarization state but also the radiation of target. With this method, the target that traditional photometry cannot detect can be settled. The degree and angle of polarization that used in polarization detection reflect different physical properties, and it is seriously redundancy along with intensity of images. A target detection method for polarization infrared image in the background of desert is proposed in allusion to the character. A modified kernel fuzzy clustering algorithm is purposed to cluster infrared images and the polarization images. Then to distinguish target from the background, the object information of clustered infrared and polarization image were combined according to sparse fusion method. Experimental results show that the proposed detection method is lower noise and more clearly details than wavelet fusion and laplacian pyramid fusion.

作者： Yanhou Zhang Shuo Wang Hao Zhai Yusheng Han Anhui Province Key laboratory of Polarized Imaging Detection Technology Department of Information Engineering Army Academy of Artillery and Air Defence Forces Hefei 230031 China

Spatial spectrum is an important tool for radar imaging performance analysis. In order to analyze the effect of spatial spectrum filling on the imaging quality of distributed passive radar, the constraints of spatial spectrum filling are studied. The imaging model of distributed passive radar is established, the imaging resolution characteristics are analyzed, and the influencing factors of spatial spectrum filling are obtained. The filling rule of spatial spectrum is analyzed, and the constraint conditions for the critical azimuth and arc of filling are given. The validity of the constraint conditions is verified by simulation, which has guiding significance for optimization of radar station layout and imaging quality improvement.

Plane measurement is an important task in image processing and computer vision. In this paper, we present a kind of plane measurement method for monocular vision, which calculates the image magnification by controlling the camera movement, the height of object and camera focal length. We can finally get the measurement results. Experimental results show that the proposed method can measure the distance more accurately. What's more, it has the advantages of high universality, simple steps and small error. © 2017 SPIE.

Artificial target has the characteristics of stronger polarization, which is found in the process of researching polarization remote sensing. So the polarization characteristics of artificial target has become one of the highlights in the research of the polarization remote sensing. Metal coating target is a kind of typical artificial target, previous studies have found that metal coating target polarization reflection characteristics vary with the condition of different observation angle and incidence angle, and the difference of polarization characteristics greatly impact the derivation and accuracy of metal material surface. In order to research the characteristics of metal coating surface bidirectional reflectance polarization, this measurement experiment set up four observation azimuth angle and nine observation zenith *** the basis of the measured data by using the semi-empirical model for data fitting, then get the data of metal coating target hemisphere space distribution of polarization reflection characteristics. This paper analyzes the relationship between target surface polarization degree and observation azimuth angle, observation zenith angle, which provides theory and data support for the derivation of typical artificial target structure features. © 2016 SPIE.

A kind of haze removal algorithm is proposed, so as to improve the visibility of degraded image with only single image. Firstly, the raw atmospheric transmission map is obtained using the dark channel prior. Then, Fields of Experts model with guided filtering is integrated to get the priors from the degraded image, so as to amend the raw atmosphere transmission map. Finally, the scene albedo is restored based on the atmosphere scattering model. Results on a variety of outdoor haze images show the feasibility and validity of our algorithm. Moreover, a comparative study is also proposed with several other state-of-the-art algorithms demonstrate that our algorithm has similar or even better haze removal results.
