Information broadcast using color space encoded image

摘要

Embodiments of the present disclosure can include systems, methods, and non-transitory computer program products for using color space encoded images to perform image-based information broadcasting. In certain aspects, the information broadcasting can include using the encoded images to broadcast information to multiple devices within view of the encoded images. Embodiments can also include broadcasting information independent of network availability. In certain aspects, a public display having a camera can register or capture a color space encoded image from a remote device, where the encoded image encodes a request for information from a user. The public display can send the encoded image to be decoded, and receive the decoded request for information. The public display can encode an encoded image representing a response, and display the encoded image representing a response for decoding by the user.

主权项

1. A computer-implemented method for broadcasting information, the method comprising:
receiving, at a capturing device, information for broadcasting; creating, at the capturing device, an image encoding the information by:
creating colored cells within a color space to provide an encoded representation of the received information in an image by processing the received information to obtain a stream of integers, each integer in the stream of integers corresponding to a color in the color space for a cell in the image; andcreating one or more additional cells, including color calibration cells, adjoining the encoded image, the one or more additional cells for assisting in decoding the encoded image by determining a pseudo-Euclidean metric in the color space, the metric measuring distance including a measure of an average of: (a) a red component in the colored cells and (b) a red component of a color in the color calibration cells; and displaying the encoded image for a plurality of devices to decode.
