Image cosegmentation and denoise. / 图像共同分割和降噪 / CUHK electronic theses & dissertations collection / Tu xiang gong tong fen ge he xiang zaoJanuary 2012 (has links)
我们提出了两个新的方法来解决低级别计算机视觉任务,即图像共同分割和降噪。 / 在共同分割模型上,我们发现对象对应可以为前景统计估计提供有用的信息。我们的方法可以处理极具挑战性的场景,如变形,角度的变化和显着不同的视角和尺度。此外,我们研究了一种新的能量最小化模型,可以同时处理多个图像。真实和基准数据的定性和定量实验证明该方法的有效性。 / 另一方面,噪音始终和高频图像结构是紧耦合的,从而使得减少噪音非常很难。在我们的降噪模型中,我们建议稍微使图像光学离焦,以减少图像和噪声的耦合。这使得我们能更有效地降低噪音,随后恢复失焦。我们的分析显示,这是可能的,并且用许多例子证明我们的技术,其中包括低光图像。 / We present two novel methods to tackle low level computer vision tasks,i.e., image cosegmentation and denoise . / In our cosegmentationmodel, we discover object correspondence canprovide useful information for foreground statistical estimation. Ourmethod can handle extremely challenging scenarios such as deformation, perspective changes and dramatically different viewpoints/scales. In addition, we develop a novel energy minimization model that can handlemultiple images. Experiments on real and benchmark data qualitatively and quantitatively demonstrate the effectiveness of the approach. / One the other hand, noise is always tightly coupled with high-frequencyimage structure, making noise reduction generally very difficult. In ourdenoise model, we propose slightly optically defocusing the image in orderto loosen this noise-image structure coupling. This allows us to more effectively reduce noise and subsequently restore the small defocus. Weanalytically show how this is possible, and demonstrate our technique on a number of examples that include low-light images. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Qin, Zenglu. / Thesis (M.Phil.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 64-71). / Electronic reproduction.
