Data storage and exchange device for color space encoded images

摘要

Embodiments of the present disclosure can include devices for storing and exchanging color space encoded images. The encoded images can store input data into high capacity multi-colored composite two-dimensional pictures having different symbols organized in specific order using sets in a color space. The encoding can include performing two-level error correction and generating frames based on the color space for formatting and calibrating the encoded images during decoding. The decoding can use the frames to perform color restoration and distortion correction. The decoding can be based on a pseudo-Euclidean distance between a distorted color and a color in a color calibration cells. In some embodiments, an encoded image can be further divided into sub-images during encoding for simplified distortion correction.

主权项

1. A device for data storage and exchange, the device comprising:
an interface for receiving data; and at least one processor configured to encode the data by
creating colored cells within a color space to provide an encoded representation of the received data in an image by processing the received data 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 image, the one or more additional cells for assisting in decoding the image by determining a pseudo-Euclidean metric in the color space, the metric measuring distance including a measure of an average of a red component in the colored cells and a red component in the color calibration cells.
