We present the ”Cartoon Animation Filter”, a simple filter that takes
an arbitrary input motion signal and modulates it in such a way that
the output motion is more ”alive” or ”animated”. The filter...
Parallax Photography: Creating 3D Cinematic Effects from Stills
Image-Based Rendering Photo and Image editing .

We present an approach to convert a small portion of a light field
with extracted depth information into a cinematic effect with simulated,
smooth camera motion that exhibits a sense of 3D parallax....

针对手指静脉图像在采集时出现的模糊现象，提出了一种基于去除皮肤散射的手指静脉图像复原算法。根据皮肤光学的实验分析，确定了手指静脉图像采集过程中皮肤对近红外光的散射模型，并自适应地进行手指静脉图像的点扩散函数的估计；再根据得到的点扩散函数采用维纳滤波完成手指静脉图像的复原。采用该算法对3幅手指静脉图像进行了复原，并对复原结果进行了定量分析，结果显示本文算法可将图像的边缘平均梯度提高3.903。最后，...
提出了一种基于极曲线几何和变支持邻域的立体匹配算法来解决鱼眼立体视觉中图像变形导致的极曲线求取和匹配代价计算问题。首先，对鱼眼相机进行标定并获取相机的相关参数；针对鱼眼镜头的畸变问题，根据鱼眼镜头的优化投影模型推导出系统的极曲线方程，并利用得到的极线方程确定对应点的搜索范围。然后，根据同源像点在左右图像上的位置关系确定各中心像素点的支持邻域，并计算出不同视差条件下该支持邻域在另一幅图像上的对应支持...
针对浮选气泡图像噪声大、边界弱、传统谷底检测算法对不同类型气泡分割不具普遍性等问题，提出了一种结合Contourlet多尺度边缘增强及自适应谷底边界检测的气泡分割方法。该方法通过对气泡图像进行Contourlet分解，得到多尺度多方向高频子带；通过对各方向子带的高频系数进行非线性增益处理，实现边缘增强和噪声抑制。对和声搜索算法的“调音”策略和参数设定方法进行了改进，对不同类型气泡图像自适应地获取谷...
