    • A computer-implemented method and system for transforming a first sequence of video frames of a first dynamic scene captured at regular time intervals to a second sequence of video frames depicting a second dynamic scene wherein for at least two successive frames of the second sequence, there are selected from at least three different frames of the first sequence portions that are spatially contiguous in the first dynamic scene and copied to a corresponding frame of the second sequence so as to maintain their spatial continuity in the first sequence. In a second aspect, for at least one feature in the first dynamic scene respective portions of the first sequence of video frames are sampled at a different rate than surrounding portions of the first sequence of video frames; and the sampled portions are copied to a corresponding frame of the second sequence.
    • 一种计算机实现的方法和系统,用于将以规则的时间间隔捕获的第一动态场景的第一视频帧序列变换为描述第二动态场景的第二视频帧序列,其中对于第二序列的至少两个连续帧, 是从在第一动态场景中在空间上连续的第一序列部分的至少三个不同帧中选择的并且被复制到第二序列的对应帧中以便保持它们在第一序列中的空间连续性。 在第二方面,对于第一动态场景中的至少一个特征,以与第一视频帧序列的周围部分不同的速率对第一视频帧序列的相应部分进行采样; 并且采样的部分被复制到第二序列的对应帧。

    • The invention relates to a method and device for generating a large static image M(n), such as a sprite or a mosaic, from a video sequence including successive video objects. This method comprises a first step for estimating motion parameters related to the current video object V0(n) of the sequence with respect to the previously generated static image M(n-1), a second step for warping this video object on the basis of the estimated motion parameters, and a third step for blending the warped video object WV0(n) thus obtained with the previously generated static image M(n-1). According to the invention, an additional step for computing, for each picture element of the current video object, a weighting coefficient WWF(n)[x,y] correlated to the error between the warped video object and the static image M(n-1) is provided, and the blending formula now takes into account said weighting coefficients.
    • 本发明涉及一种用于从包括连续视频对象的视频序列生成诸如子画面或马赛克的大静态图像M(n)的方法和装置。 该方法包括:第一步骤,用于相对于先前产生的静态图像M(n-1)估计与序列的当前视频对象V0(n)相关的运动参数;第二步骤,用于基于 估计运动参数,以及用于将由此获得的翘曲视频对象WV0(n)与先前产生的静态图像M(n-1)进行混合的第三步骤。 根据本发明,对于当前视频对象的每个图像元素,计算与翘曲视频对象与静态图像M(n-1)之间的误差相关的加权系数WWF(n)[x,y] 1),并且混合公式现在考虑到所述加权系数。

    • A system and method of providing composite real-time dynamic imagery of a medical procedure site from multiple modalities which continuously and immediately depicts the current state and condition of the medical procedure site synchronously with respect to each modality and without undue latency is disclosed. The composite real-time dynamic imagery may be provided by spatially registering multiple real-time dynamic video streams from the multiple modalities to each other. Spatially registering the multiple real-time dynamic video streams to each other may provide a continuous and immediate depiction of the medical procedure site with an unobstructed and detailed view of a region of interest at the medical procedure site at multiple depths. As such, a surgeon, or other medical practitioner, may view a single, accurate, and current composite real-time dynamic imagery of a region of interest at the medical procedure site as he/she performs a medical procedure, and thereby, may properly and effectively implement the medical procedure.

    • The video summarization system and method supports a moving sensor or multiple sensors by mapping imagery back to a common ortho-rectified geometry. The video summarization system includes at least one video sensor to acquire video data, of at least one area of interest (AOI), including video frames having a plurality of different perspectives. The video sensor may be a moving sensor or a plurality of sensors to acquire video data, of the at least one AOI, from respective different perspectives. A memory stores the video data, and a processor is configured to cooperate with the memory to register video frames from the AOI, ortho-rectify registered video frames based upon a common geometry, identify events within the ortho-rectified registered video frames, and generate a video summary of selected events shifted in time within a selected AOI based upon identified events within the ortho-rectified registered video frames.
