Techniques are disclosed to identify a form document in an image using a digital fingerprint of the form document. To do so, the image is evaluated to detect features of the image and determine a polygon bounding each feature. For each polygon, pixels are plotted in a second image based on coordinates of a center of the polygon. The second image is the digital fingerprint of the form. To identify the form corresponding to the digital fingerprint, the digital fingerprint may be compared to digital fingerprints of known forms.

Techniques are disclosed to identify a form document in an image using a digital fingerprint of the form document. To do so, the image is evaluated to detect features of the image and generate a boundary around each feature. For each boundary, dimensions of the boundary may be stored in a color channel of a pixel in a second image. Thus, the color of the pixel represents the size of the boundary. The second image is the digital fingerprint of the form. To identify the form corresponding to the digital fingerprint, the digital fingerprint may be compared to digital fingerprints of known forms.

There is provided an information processing apparatus comprising: a storage unit configured to store a plurality of process modules including a first process module for performing an embedding process by which information is embedded in image data; a setting unit configured to set a condition for performing the embedding process by the first process module; and a controlling unit configured to control a workflow in which one or more processes respectively performed by the process modules, including the first process module, are sequentially performed; wherein the first process module performs the embedding process under the set condition in response to detecting that image data input to the first process module in controlling the workflow is in a preset image format.

An image forming system includes: an image forming apparatus including an image forming unit for forming an image on a sheet, an image reading unit for reading a sheet surface and generating a scan image, an image inspection unit for detecting abnormalities within the scan image, and a history generating unit for generating detection information of each of the abnormalities and generating a history image by embedding the detection information in the scan image; a storage device for storing the history image; and a user terminal for displaying an abnormality detection result and inputting a user's evaluation of the abnormality detection result, wherein the image forming apparatus further includes a parameter setting unit for finally determining the abnormalities depending on the user's evaluation, and determining and setting abnormality detection parameters such that the abnormalities finally determined are detected, and the abnormalities not finally determined are not detected.

This disclosure relates to advanced image signal processing technology including encoded signals and digital watermarking. We disclose methods, systems and apparatus for selecting which ink(s) should be selected to carry an encoded signal for a given machine-vision wavelength for a retail package or other printed design. We also disclose retail product packages and other printed objects, and methods to generate such, including a sparse mark in a first ink and an overprinted ink flood in a second ink. The first ink and the second ink are related through tack and spectral reflectance difference. Of course, other methods, packages, objects, systems and apparatus are described in this disclosure.
