摘要： Visual discomfort from depth jumps in 3D video content is reduced or avoided by detecting the occurrence of a depth jump and by Input video changing the disparity of a group of received image frames including the frames at the depth jump in order to adjust the perceived depth in a smooth transition across the group of image frames from a first disparity value to a second disparity value. Depth jumps may be detected, for instance, when content is switched from one 3D shot to another 3D shot.
摘要翻译：通过检测深度跳跃的发生和通过输入视频改变包括深度跳跃中的帧的接收的图像帧的视差来减少或避免3D视频内容中的深度跳跃的视觉不适，以便调整深度跳跃的感知深度跨越一组图像帧从第一视差值到第二视差值的平滑过渡。例如，当内容从一个3D镜头切换到另一个3D镜头时，可以检测到深度跳跃。

摘要： A method comprises receiving original encoded video stream as one input, accessing encoded data divided into slices which are further divided into blocks, receiving the list of possible changes or watermarks as another input, accessing at least one block, decoding each slice, setting down each slice, extracting from the list those changes that apply to the at least one block, and constructing propagation maps from inter-prediction or intra-prediction using changes for the at least one block. The method can further comprise decoding luminance data using the propagation maps, comparing the luminance data to a fidelity threshold, and applying possible changes or watermarks to those not exceeding the fidelity threshold.
