Abstract

Features from a style image are adapted to express a machine-readable code. For example, grains of rice depicted in a style image may be positioned to create a pattern mimicking that of a machine-readable code. The resulting output image can then be used as a graphical component in product packaging (e.g., as a background, border, or pattern fill), while also serving to convey a product identifier to a compliant reader device (e.g., a retail point-of-sale terminal). In some embodiments, a neural network is trained to apply a particular style image to machine readable codes. A great variety of other features and arrangements are also detailed.

First claim

1 - 4 . (canceled)

5 . A method comprising the acts:
digitally-watermarking a first image to encode a plural-bit payload therein, yielding a second image; and neural network processing the second image to i) reduce a difference measure between the processed second image and a style image, or ii) increase a similarity measure between the processed second image and the style image.

6 . The method of claim 5 in which the difference measure is based on a difference between a Gram matrix for the processed second image and a Gram matrix for the style image.

7 . The method of claim 6 that includes incorporating some or all of the processed second image within label artwork for food product packaging.

8 . The method of claim 5 in which the plural-bit payload is recoverable by a digital watermark decoder from the neural network processed second image.

9 . A method comprising the acts:
receiving a pattern that encodes a plural-symbol payload; and applying a style to said pattern, using a previously-trained neural network, to produce a stylized output image, the style being based on a style image having various features, wherein the network adapts features from the style image to express details of the received pattern, to thereby produce an image in which features from the style image contribute to encoding of said plural-symbol payload.

10 . The method of claim 9 in which said applying act comprises applying said pattern to a neural network that has been previously-trained with a style image using the method of Johnson.

11 - 29 . (canceled)

30 . A method for producing a code for message signaling through an image, the method employing a deep neural network, the deep neural network having an input, one or more outputs, and plural intermediate layers, each layer of the plural intermediate layers comprising plural filters, each filter of the plural filters characterized by plural parameters that define a response of the filter to a given input, the method comprising the acts:
iteratively adjusting an input test image, based on results produced by the filters of said neural network, until the test image adopts both (1) style features from one image, and (2) signal-encoding features from a second image; and outputting an iteratively adjusted input test image, the iteratively adjusted input test image comprising the signal-encoding features, in which the signal-encoding features are machine-readable from the iteratively adjusted input test image.
