The present disclosure is directed toward systems and methods to quickly and accurately identify boundaries of a displayed document in a live camera image feed, and provide a document boundary indicator within the live camera image feed. For example, systems and methods described herein utilize different display document detection processes in parallel to generate and provide a document boundary indicator that accurately corresponds with a displayed document within a live camera image feed. Thus, a user of the mobile computing device can easily see whether the document identification system has correctly identified the displayed document within the camera viewfinder feed.

Live document detection in a captured video stream

The present disclosure is directed toward systems and methods that efficiently and effectively generate an enhanced document image of a displayed document in an image frame captured from a live image feed. For example, systems and methods described herein apply a document enhancement process to a displayed document in an image frame that result in an enhanced document image that is cropped, rectified, un-shadowed, and with dark text against a mostly white background. Additionally, systems and method described herein determine whether a stored digital content item includes a displayed document. In response to determining that a stored digital content item does include a displayed document, systems and methods described herein generate an enhanced document image of a displayed document included in the stored digital content item.

Enhancing documents portrayed in digital images

A wireless charging resource includes: processing elements; insulating elements; and coils, where the processing elements, insulating elements, and coils are arranged in a repeating array. A method of wireless charging includes: sending, from a charging resource, an analog ping to identify charging coils associated with a charging receiver; sending a digital ping to identify optimal charging coils; and activating the optimal charging coils in order to provide charging power to the charging receiver. A method of generating a layout for a wireless charging transmitter includes: determining an available area; calculating a number of coils to be included in an array; arranging a first set of coils including the number of coils on a first coil layer; arranging a second set of coils including the number of coils on a second coil layer; and arranging a third set of coils including the number of coils on a third coil layer.

In response to determining that a stored digital content item does include a displayed document, systems and methods described herein generate an enhanced document image of a displayed document included in the stored digital content item.

A system provides communication among user devices and Internet of things (IoT) devices includes a user device able to execute at least one application that is able to communicate using at least a first IoT protocol; an IoT device able to communicate using at least a second IoT protocol; and a universal translator able to communicate using at least the first IoT protocol and the second IoT protocol. An automated method of providing communications between a user device and an IoT device includes: determining a protocol of the IoT device; determining a protocol of the user device; and inserting a virtual device if the protocols are different. An automated method of translating communications for IoT systems includes: receiving a device protocol and identifier; receiving an application protocol and identifier; adding the application identifier to an application list; and adding the device identifier to a device list.

Universal internet of things (IoT) smart translator

An automated method of detecting measurement inaccuracy in an air quality detection system includes: receiving an air quality measurement from at least two sensors; determining a difference among the received air quality measurements; and comparing the difference to a threshold value. A system that detects measurement inaccuracy in an air quality detection includes: multiple smart residue avoidance and inaccuracy detection (SRAID) devices; and a server. An SRAID device includes: a plurality of air quality detection sensors; a controller able to: receive measurements from the plurality of air quality detection sensors; calculate a difference among the received measurements; and generate a notification if the difference exceeds a threshold value; and a communication module able to communicate with at least one of a server and an air flow controller device.
