Abstract: A virtual browsing experience may be implemented that allows a user to move a mobile device within a physical environment in order to control browser navigation to different items on an associated display. The virtual browsing experience improves the user's ability to recall where previously-viewed items are located in the virtual browsing environment. In some embodiments, a mobile device may determine its position and/or orientation in a physical environment, and when movement of the mobile device is detected, a user interface on an associated display may digitally navigate through multiple items according to the position and/or orientation of the mobile device. The position and orientation of the mobile device may be determined from position information or data obtained by a sensor device of the mobile device, and appropriate subsets of items can be determined for display based on detected movement of the mobile device.

Abstract: 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.

Abstract: Embodiments of the subject technology provide for a hybrid OCR approach which combines server and device side processing that can offset disadvantages of performing OCR solely on the server side or the device side. More specifically, the subject technology utilizes image characteristics such as glyph details and image quality measurements to opportunistically schedule OCR processing on the mobile device and/or server. In this regard, text extracted by a “faster” OCR engine (e.g., one with less latency) is displayed to a user, which is then updated by the result of a more accurate OCR engine (e.g., an OCR engine provided by the server). This approach allows factoring in additional parameters such as network latency and user preference for making scheduling decisions. Thus, the subject technology may provide significant gains in terms of reduced latency and increased accuracy by implementing one or more techniques associated with this hybrid OCR approach.
Abstract translation: 本技术的实施例提供了一种组合服务器和设备侧处理的混合OCR方法，其可以抵消仅在服务器侧或设备侧执行OCR的缺点。 更具体地，本主题技术利用诸如字形细节和图像质量测量的图像特征来机会地在移动设备和/或服务器上调度OCR处理。 在这方面，由“更快的”OCR引擎提取的文本（例如，具有较小延迟的引擎）被显示给用户，然后由更准确的OCR引擎（例如，由服务器提供的OCR引擎）的结果来更新 ）。 这种方法允许考虑附加参数，例如网络延迟和用户偏好以进行调度决策。 因此，本技术可以通过实施与该混合OCR方法相关联的一种或多种技术在减少的延迟和增加的准确性方面提供显着的增益。

Abstract: Various embodiments describe systems and methods for utilizing a reduced amount of processing capacity for incoming data over time, and, in response to detecting a scene-change-event, notify one or more data processors that a scene-change-event has occurred, and cause incoming data to be processed as new data. In some embodiments, an incoming frame can be compared with a reference frame to determine a difference between the reference frame and the incoming frame. The reference frame may be correlated to a latest scene-change-event. In response to a determination that the difference does not meet one or more difference criteria, a user interface or at least one processor of the computing device can be notified to reduce processing of incoming data over time. In response to a determination that the difference meets the one or more difference criteria, the user interface or the at least one processor can be notified that a scene-change-event has occurred. Incoming data to the computing device is then treated as new and processed as those under an active condition. The current incoming frame can be selected as a new reference frame for detecting next scene-change-event.
