Abstract: A system, method, and computer program product for selecting qualifying frames from an image sequence for use in subsequent stitching into a composite panoramic image are disclosed. Incoming frames from any source may be cropped and downscaled prior to evaluation against qualifying criteria relating to image overlap and local motion. Qualifying images are saved and/or output. The resulting panoramic image generally uses fewer qualifying images and appears smoother and has fewer artifacts than those of the prior art. The qualifying criterion for image overlap is a predetermined overlap margin or percentage between a current image and a previous image from the sequence. The qualifying criterion for image motion includes a maximum amount of local motion, often due to passing objects. The embodiments may process incoming images in real time or from stored sequences. Problems may trigger user warnings.

Abstract translation: 公开了一种用于从用于随后拼接成复合全景图像的图像序列中选择合格帧的系统，方法和计算机程序产品。 在对与图像重叠和局部运动有关的限定标准进行评估之前，来自任何来源的进帧可以被裁剪和缩小。 合格图像被保存和/或输出。 所得到的全景图像通常使用较少的限定图像，并且看起来更平滑并且具有比现有技术更少的伪影。 图像重叠的限定条件是当前图像与来自该序列的先前图像之间的预定重叠余量或百分比。 图像运动的限定标准包括局部运动的最大量，这通常是由于传递的对象。 这些实施例可以实时地或从存储的序列处理输入的图像。 问题可能会触发用户警告。
