摘要： Various embodiments utilize two-dimensional (“2D”) and three-dimensional (“3D”) object features for purposes such as object recognition and/or image matching. For example, a user can capture an image (e.g., still images or video) of an object and can receive information about items that are determined to match the object. For example, the image can be analyzed to detect visual features (e.g., corners, edges, etc.) of the object and the detected visual features can be combined to generate a combined visual feature vector which can be used for object recognition, image matching, or other such purposes. Other approaches utilize the image to generate a 3D model of the object represented in the image, which can be used to determine at least one object or types of objects that match the object represented in the image.

摘要： This disclosure describes a system for tracking removal or placement of items at inventory locations with a materials handling facility. In some instances, a user may remove an item from an inventory location and the inventory management system may detect that removal and update a user item list associated with the user to include an item identifier representative of the removed item. Likewise, if the user places an item at an inventory location, the inventory management system may detect that placement and update the user item list to remove an item identifier representative of the placed item.

摘要： Systems and approaches are provided for obtaining high quality image data from lower resolution and/or lower quality image data. An electronic device can be calibrated comprehensively prior to being provided to a user. The calibrated electronic device can be used to capture image data, image metadata, and other sensor data substantially simultaneously. Super-resolution processing can be applied to the captured image data to obtain higher quality image data than the captured image data, such as image data that corresponds to a higher resolution, has less blur, has less noise, has fewer photometric imperfections, and/or has fewer artifacts.

摘要： A mobile device for projecting images on a surface and for maintaining a position of the image on the surface. The device including an image rendering module to scan the surface and to modify the image based on data obtained about a three dimensional nature of the surface. The device further including an optical image stabilization to adjust an alignment of the projector based on orientation data of the device, an electronic image stabilization module to shift the image within a projection area based on the orientation data and an image-tracking module to shift the image within the projection area based on changes in a relative positions of the image and a target.

摘要： Various embodiments enable a computing device to capture multiple images (or video) of text and provide at least a portion of the same to a recognizer to separately recognize text from each image. Each of the recognized outputs will typically include one or more text strings for each image. Substrings common to each of the one or more text strings are computed and compared to each text string within each image to determine an alignment consensus for each substring within the text. A template string is generated that includes each common substring in a position corresponding to a determined alignment for a respective substring. A character frequency vote is then applied to unresolved portions and the final text string is determined by filling the unresolved spaces with the character having the highest occurrence rate for a respective space.

摘要： Embodiments of the subject technology provide methods and systems of image pre-processing for improving the accuracy of optical character recognition (OCR) and reducing the power consumption on a given computing device (e.g., mobile computing device). The subject technology, in some examples, classifies an image received from a camera of a mobile computing device into one or more classes: 1) normal background, 2) textured background, 3) image with text, 4) image with barcode, 5) image with QR code, and/or 6) image with clutter or “garbage.” Based on the classes associated with the image, the subject technology may forgo certain image processing operations, when the image is not associated with a particular class, in order to save resources (e.g., CPU cycles, battery power, memory usage, etc.) on the mobile computing device.
摘要翻译：主题技术的实施例提供了用于提高光学字符识别（OCR）的精度并降低给定计算设备（例如，移动计算设备）的功耗的图像预处理的方法和系统。在一些示例中，主题技术将从移动计算设备的相机接收的图像分类为一个或多个类别：1）正常背景，2）纹理背景，3）具有文本的图像，4）具有条形码的图像，5）具有QR码的图像和/或6）具有杂波或“垃圾”的图像。基于与图像相关联的类别，当图像与特定类别不相关时，主题技术可以放弃某些图像处理操作以在移动计算设备上节省资源（例如，CPU周期，电池电量，存储器使用等）。
