Abstract: The methods and systems of the present invention enable the estimation of optical flow by performing color segmentation and adaptive bilateral filtering to regularize the flow field to achieve a more accurate flow field estimation. After creating pyramid models for two input image frames, color segmentation is performed. Next, starting from a top level of the pyramid, additive flow vectors are iteratively estimated between the reference frames by a process including occlusion detection, wherein the symmetric property of backward and forward flow is enforced for the non-occluded regions. Next, a final estimated optical flow field is generated by expanding the current pyramid level to the next lower level and the repeating the process until the lowest level is reached. This approach not only generates efficient spatial-coherent flow fields, but also accurately locates flow discontinuities along the motion boundaries.

Abstract: A method for transforming Video-To-Text is disclosed that automatically generates text descriptions of the content of a video. The present invention first segments an input video sequence according to predefined semantic classes using a Mixture-of-Experts blob segmentation algorithm. The resulting segmentation is coerced into a semantic concept graph and based on domain knowledge and a semantic concept hierarchy. Then, the initial semantic concept graph is summarized and pruned. Finally, according to the summarized semantic concept graph and its changes over time, text and/or speech descriptions are automatically generated using one of the three description schemes: key-frame, key-object and key-change descriptions.

Abstract: Selective replacement methods and systems based on a stochastic process use a redundancy inherent, for example, in a four-plus color printing system that has full-width colors. Since the absorption spectra of the four or more colors usually overlap to some extent, there is a redundancy that can be used to reduce artifacts, such as streaks. Since the human visual system is much less sensitive to chrominance changes, than to luminance changes, matching the luminance of a pixel where a color is missing, to the luminance of the original color or to the luminance of the pixels that neighbor that pixel can adequately to reduce the severity of the artifact caused by the missing color while reducing the chance that the replacing process itself introduces any additional artifacts.

Abstract translation: 基于随机过程的选择性替换方法和系统使用固有的冗余，例如在具有全宽颜色的四色彩色打印系统中。 由于四种或更多种颜色的吸收光谱通常在一定程度上重叠，所以存在可用于减少伪像（例如条纹）的冗余。 由于人类视觉系统对于色度变化的敏感程度要比亮度变化（匹配缺失颜色的像素的亮度）与原始颜色的亮度或邻近该像素的像素的亮度相匹配 以减少由缺失颜色引起的伪像的严重性，同时减少替换过程本身引入任何其他工件的机会。

Abstract: A computer implemented method for determining a vehicle type of a vehicle detected in an image is disclosed. An image having a detected vehicle is received. A number of vehicle models having salient feature points is projected on the detected vehicle. A first set of features derived from each of the salient feature locations of the vehicle models is compared to a second set of features derived from corresponding salient feature locations of the detected vehicle to form a set of positive match scores (p-scores) and a set of negative match scores (n-scores). The detected vehicle is classified as one of the vehicle models models based at least in part on the set of p-scores and the set of n-scores.
