1. The approximate invariance of the middle frequencies energy relationship between video adjacent frames under photometric distortion and spatial desynchronization is discovered by analysis. 通过分析发现了视频帧问中频能量关系对于光度失真和空间同步失真的近似不变性。2) optical distortion 光失真<光>...
Again, in this more general case, while an access to automatic computers may be of advantage to incorporate the photometric perturbation arising from the distortion of the components mutually eclipsing each other, their use represents a convenience rather than necessity for our work....
Lens barrel distortion can affect analysis accuracy. The DCA package enables users to correct distortion using a control pattern of evenly spaced points, customized for specific lens and distance settings. Learn More Although our software packages can be used for multiple applications, they are specifi...

(i+1)−2, where τ is the gravity darkening coefficient and i is the limb-darkening index – 0 for undarkened, 1 for a linear cosine law, 2 for a squared cosine law and so on – while j is the order of the relevant spherical harmonic, the full distortion being expressed as a ...
the total accumulated axial distortion would be of about 10 nm (Supplementary Fig.1c). It should be noted that these are total accumulated distortions smaller than 4%, hardly noticeable and probably surpassed by other factors such as the size or the position of the labels. Overall, the rob...
The wave-like distortion was removed with a new approach. Then, the light curves were analyzed by the methods of Wood and Nelson, Davis, and Etzel. The absolute parameters of the components were also calculated. The physical parameters of the components indicate that the cooler star has ...
The experimental results indicate that our method can effectively correct the distortion in underwater 3-D reconstruction. 展开 关键词: refractive model laser triangulation photometric stereo DOI: 10.1117/1.OE.56.11.113101 年份: 2017 收藏 引用 批量引用 报错 分享 ...
[18] that the use of an orthographic camera model may yield visible distortion in the reconstruction while a perspective model may take the geometry better into account: see the experiment documented in Fig. 2; note that the object of interest is relatively close to the camera. This justifies...
We present a system to restore the 2D content printed on distorted documents. Our system works by acquiring a 3D scan of the document?s surface together with a high-resolution image. Using the 3D surface information and the 2D image, we can ameliorate unwanted surface distortion and effects fr...
