Abstract: A document inspection system performs texture analysis on a portion of a first image that represents a first document and on a portion of a second image that represents a second document; performing. Feature vectors for the regions from the first and second documents are compared. If the feature vectors have a threshold degree of similarity, they may be identified as being sufficiently related. This may have applicability, for example, in determining with a first document is valid because reflects sufficiently-similar characteristics to those of a reference document.

Abstract: A method for detecting images of fraudulently generated or photocopied secure credential documents using texture analysis includes receiving, by one or more processors, an image of a secure credential document from a computer device. The one or more processors segment the image of the secure credential document into multiple regions. For each region of the multiple regions, the one or more processors extract local high-resolution texture features from the image of the secure credential document. The one or more processors generate a score based on the local high-resolution texture features using a machine learning model. The score is indicative of a likelihood that the image of the secure credential document is fraudulently generated or photocopied. The one or more processors transmit a message to a display device indicating that the image of the secure credential document is fraudulently generated or photocopied.

Abstract: Among other things, a texture of an image is characterized by deriving entropy-based lacunarity parameters from density distributions generated from the image based on a wavelet analysis. In some examples, lacunarity descriptors are extracted from textured regions using wavelet maxima. The distributions of the local wavelet maxima density in a sliding window over the region of interest are compared using different methods in order to generate lacunarity parameters.
