摘要： A system and a method are disclosed for an adaptive discriminative generative model with a probabilistic interpretation. As applied to visual tracking, the discriminative generative model separates the target object from the background more accurately and efficiently than conventional methods. A computationally efficient algorithm constantly updates the discriminative model over time. The discriminative generative model adapts to accommodate dynamic appearance variations of the target and background. According to an alternate embodiment, visual tracking is formulated by defining an object class and one or more background classes. The most discriminant features available in the images are then used to select a portion of each image as belonging to the object class. Fisher's linear discriminant method is used to project high-dimensional image data onto a lower-dimensional space, e.g., a line, and perform classification in the lower-dimensional space. The projection function is incrementally updated.

摘要： The face detection system and method attempts classification of a test image before performing all of the kernel evaluations. Many subimages are not faces and should be relatively easy to identify as such. Thus, the SVM classifier try to discard non-face images using as few kernel evaluations as possible using a cascade SVM classification. In the first stage, a score is computed for the first two support vectors, and the score is compared to a threshold. If the score is below the threshold value, the subimage is classified as not a face. If the score is above the threshold value, the cascade SVM classification function continues to apply more complicated decision rules, each time doubling the number of kernel evaluations, classifying the image as a non-face (and thus terminating the process) as soon as the test image fails to satisfy one of the decision rules. Finally, if the subimage has satisfied all intermediary decision rules, and has now reached the point at which all support vectors must be considered, the original decision function is applied. Satisfying this final rule, and all intermediary rules, is the only way for a test image to garner a positive (face) classification.
摘要翻译：面部检测系统和方法在执行所有内核评估之前尝试对测试图像进行分类。许多子图像不是面孔，应该比较容易识别。因此，SVM分类器尝试使用级联SVM分类尽可能少地使用内核评估来丢弃非面部图像。在第一阶段，对前两个支持向量计算分数，并将分数与阈值进行比较。如果分数低于阈值，则子图像被分类为不是脸部。如果分数高于阈值，则级联SVM分类功能继续应用更复杂的决策规则，每次将内核评估的数量加倍，将图像分类为非面（并因此终止进程），一旦测试图像不能满足其中一个决策规则。最后，如果子图像满足了所有的中介决策规则，并且现在已经到了必须考虑所有支持向量的点，则应用原始决策函数。满足这个最终规则和所有中介规则是测试图像获得积极（面部）分类的唯一方法。

摘要： A system and a method are disclosed for clustering (370) images of objects seen from different viewpoints. That is, given an unlabelled set of images of n objects (310), an unsupervised algorithm groups the images into N disjoint subsets such that each subset only contains images of a single object. The clustering method makes use of a broad geometric framework that exploits the interplay between the geometry of appearance manifolds and the symmetry of the 2D affine group.

摘要： A system and a method model the motion of a non-rigid object using a thin plate spline (TPS) transform. A first image of a video sequence is received, and a region of interest, referred to as a template, is chosen manually or automatically. A set of arbitrarily-chosen fixed reference points is positioned on the template. A target image of the video sequence is chosen for motion estimation relative to the template. A set of pixels in the target image corresponding to the pixels of the template is determined, and this set of pixels is back- warped to match the template using a thin-plate-spline-based technique. The error between the template and the back-warped image is determined and iteratively minimized using a gradient descent technique. The TPS parameters can then be used to estimate the relative motion between the template and the corresponding region of the target image. According to one embodiment, a stiff-to-flexible approach mitigates instability that can arise when reference points lie in textureless regions, or when the initial TPS parameters are not close to the desired ones. The value of a regularization parameter is varied from a larger to a smaller value, varying the nature of the warp from stiff to flexible, so as to progressively emphasize local non-rigid deformations.
摘要翻译：系统和方法使用薄板样条（TPS）变换来模拟非刚性物体的运动。接收视频序列的第一图像，并且手动或自动选择被称为模板的感兴趣区域。一组任意选择的固定参考点位于模板上。视频序列的目标图像被选择用于相对于模板的运动估计。确定目标图像中与模板的像素相对应的一组像素，并且使用基于薄板样条的技术来对这组像素进行反向翘曲以匹配模板。使用梯度下降技术确定模板和反向变形图像之间的误差并迭代最小化。然后可以使用TPS参数来估计模板与目标图像的对应区域之间的相对运动。根据一个实施例，当参考点位于无纹理区域中时，或者当初始TPS参数不接近期望值时，刚性到柔性方法减轻可能出现的不稳定性。正则化参数的值从较大值变化到较小值，从而使经线的性质从刚性变为柔性，从而逐渐强调局部非刚性变形。

摘要： A system (and a method) are disclosed for recognizing and representing activities in a video sequence. The system includes an activity dynamic Bayesian network (ADBN), an object/action dictionary, an activity inference engine and a state output unit. The activity dynamic Bayesian network encodes the prior information of a selected activity domain. The prior information of the selected activity domain describes the ordering, temporal constraints and contextual cues among the expected actions. The object/action dictionary detects activities in each frame of the input video stream, represents the activities hierarchically, and generates an estimated observation probability for each detected action. The activity inference engine estimates a likely activity state for each frame based on the evidence provided by the object/action dictionary and the ADBN. The state output unit outputs the likely activity state generated by the activity inference engine.
