Text detection near display screen edge

摘要

Approaches to enable a computing device, such as a phone or tablet computer, to detect when text contained in an image captured by the camera is sufficiently close to the edge of the screen and to infer whether the text is likely to be cut off by the edge of the screen such that the text contained in the image is incomplete. If the incomplete text corresponds to actionable text associated with a function that can be invoked on the computing device, the computing device may wait until the remaining portion of the actionable text is captured by the camera and made available for processing before invoking the corresponding function on the computing device.

1. A computing device, comprising:
a camera configured to capture an image; a display screen configured to display the image captured by the camera; at least one processor; and memory including instructions that, when executed by the at least one processor, cause the computing device to:
detect one or more glyphs in the image;determine a distance between a first glyph of the one or more glyphs and an edge of the image;transmit the distance and image data containing the one or more glyphs to a server for processing by an optical character recognition (OCR) engine, wherein the server is configured to: analyze the image data, determine actionable text corresponding to the one or more glyphs is likely to be incomplete based at least in part on one or more characteristics of the actionable text and the distance, wherein the one or more characteristics of the actionable text include at least one of a character size of the actionable text, a font of the actionable text, a height of the actionable text, or a spacing between each character of the actionable text;receive a communication from the server indicating that the actionable text is likely to be incomplete; anddisplay a graphical indication on the display screen indicating that the actionable text is likely to be incomplete.
