    Abstract: In some arrangements, product packaging is digitally watermarked over most of its extent to facilitate high-throughput item identification at retail checkouts. Imagery captured by conventional or plenoptic cameras can be processed (e.g., by GPUs) to derive several different perspective-transformed views—further minimizing the need to manually reposition items for identification. Crinkles and other deformations in product packaging can be optically sensed, allowing such surfaces to be virtually flattened to aid identification. Piles of items can be 3D-modelled and virtually segmented into geometric primitives to aid identification, and to discover locations of obscured items. Other data (e.g., including data from sensors in aisles, shelves and carts, and gaze tracking for clues about visual saliency) can be used in assessing identification hypotheses about an item. A great variety of other features and arrangements are also detailed.

    Abstract translation: 在一些安排中,产品包装在其大部分程度上以数字水印方式,以促进零售结算处的高通量物品识别。 可以通过传统或全光照相机拍摄的图像(例如,通过GPU)来处理几个不同的透视变换视图 - 进一步最小化手动重新定位项目以进行识别的需要。 产品包装中的皱纹和其他变形可以光学感测,允许这些表面几乎变平,以帮助识别。 物品堆可以3D建模,并将其虚拟分割成几何图元,以帮助识别,并发现隐藏物品的位置。 可以使用其他数据(例如,包括来自在通道中的传感器的数据,架子和推车以及关于视觉显着性的线索的凝视跟踪)来评估关于物品的识别假设。 还详细介绍了各种各样的其他功能和安排。
