摘要： A system and method are provided for tracking a face moving through multiple frames of a video sequence. A predicted position of a face in a video frame is obtained. Similarity matching for both a color model and an edge model are performed to derive correlation values for each about the predicted position. The correlation values are then combined to determine a best position and scale match to track a face in the video.

摘要： A system and method initializes objects in video data. In an embodiment, the video data is an output of a video tracker, and in a particular embodiment, the video tracker is a particle filter. A histogram is calculated that indicates a number of particles that do not cover an object in an input image from the particle filter at a position in the input image. The system and method then initializes an object to be tracked in the input image as a function of the histogram.
摘要翻译：系统和方法初始化视频数据中的对象。在一个实施例中，视频数据是视频跟踪器的输出，并且在特定实施例中，视频跟踪器是粒子滤波器。计算直方图，其指示在输入图像中的位置处不包括来自粒子滤波器的输入图像中的物体的数量的粒子。然后，系统和方法根据直方图初始化输入图像中要跟踪的对象。

摘要： An object detection method and system for detecting an object in an image utilizing an adaptive image scanning strategy is disclosed herein. An initial rough shift can be determined based on the size of a scanning window and the image can be scanned continuously for several detections of similar sizes using the rough shift. The scanning window can be classified with respect to a cascade of homogenous classification functions covering one or more features of the object. The size and scanning direction of the scanning window can be adaptively changed depending on the probability of the object occurrence in accordance with scan acceleration. The object can be detected by an object detector and can be localized with higher precision and accuracy.
摘要翻译：本文公开了一种使用自适应图像扫描策略来检测图像中的物体的物体检测方法和系统。可以基于扫描窗口的大小来确定初始粗略位移，并且可以使用粗移位来连续扫描图像以进行几次相似尺寸的检测。扫描窗口可以相对于涵盖对象的一个或多个特征的均匀分类函数的级联来分类。扫描窗口的尺寸和扫描方向可以根据扫描加速度的对象发生的概率自适应地改变。物体可以被物体检测器检测到，并且可以以更高的精度和精度进行定位。
