Description: In this paper we present a scheme for integrating a digital stabilizer with video codec of a digital video camera. This integration achieves computational efficiency without affecting the performance of video coding and digital stabilization. The proposed scheme achieves this by confining the global motion estimation to within a small background region determined by clustering the motion vectors generated by the video encoder.- In this paper we present a scheme for integrating a digital stabilizer with video codec of a digital video camera.

Description: 机载电子稳像技术研究，很好的一篇博士论文。
本章首先分析了航摄动态图像的特点，并在对机载航摄图像序列进行大量的实
验和理论分析的基础上，提出了适用机载视频图像序列稳定的有效算法，即灰度投影

Description: This tutorial reviews image alignment and image stitching algorithms. Image align-
ment (registration) algorithms can discover the large-scale (parametric) correspon-
dence relationships among images with varying degrees of overlap. They are ideally
suited for applications such as video stabilization, summarization, and the creation
of large-scale panoramic photographs. Image stitching algorithms take the alignment
estimates produced by such registration algorithms and blend the images in a seam-
less manner, taking care to deal with potential problems such as blurring or ghosting
caused by parallax and scene movement as well as varying image exposures. This tu-
torial reviews the basic motion models underlying alignment and stitching algorithms,
describes effective direct (pixel-based) and feature-based alignment algorithms, and
describes blending algorithms used to produce seamless mosaics. It closes with a dis-
cussion of open research problems in the area. Platform: |

Description: 手持式摄像机在使用时常常会受到使用者有意无意抖动的影响,从而影响成像效果，造成录制视频的不稳定及跳动问题，尤其是在使用者在一场景中特写或者跟踪某一具体目标时，使用者通常不能准确定位到或者估计出运动目标的位置，从而造成目标在视频中位置的不稳定，造成视频的主观效果变得不理想。
为了解决这一问题，我们需要设计一种算法来识别这种无意义的运动并设法通过补偿的方式来使得场景中的目标物体保持位置稳定的状态。
手持式摄像机捕获的视频通常都会受到抖动的影响，这严重的影响视频的主观效果。
这里提出的算法可以可靠的用于数字视频的去抖动。这个算法通过识别这些意外的抖动并且利用运动补偿的方法来获得一个较好的视频输出。
这个系统可以分为三个模块：（1）运动估计模块；（2）抖动识别模块；（3）运动补偿模块。

[1] F Vella, A Castorina, M Mancuso. Digital image stabilization by adaptive block motion vectors filtering, IEEE Transactions on Consumer Electronics, 2002-Handheld cameras are often used by the user intentionally or unintentionally, the influence of jitter affect the imaging results, resulting in instability and beat the problem of recording video, and especially in the user in a scene close-up or tracking a specific target,users often can not accurately navigate to estimate the location of the moving target, resulting in the subjective effects of target location of the instability in the video, resulting in video not ideal.
In order to solve this problem, we need to design an algorithm to identify such a meaningless exercise and try to make the object in the scene to keep the position stable state by way of compensation.
The handheld camera captured video usually subject to the influence of jitter, the subjective effect of which seriously affect the video.
The algorithm proposed here can be reliably used for digital video to jitter. This algorithm by identifying the jitter of these accidents and the use of motion compensation m Platform: |
