Material classification fused with spatio-spectral edge detection in spectral imagery

摘要

Apparatus, systems, and methods fusing material classification with spatio-spectral edge detection in spectral imagery can be used in a variety of applications. In various embodiments, a classifier can be applied to neighboring pixels in data for an image to determine, based on material changes, if the neighboring pixels are correlated to two different materials with respect to a candidate location for an edge. Results of the classification can be used with a spatio-spectral mask to accept or reject the candidate location as an edge. Additional apparatus, systems, and methods are disclosed.

1. A method comprising:
acquiring data of an image; processing the data including identifying a candidate location of an edge between two materials in the image, the data having neighboring pixels defining a portion of the candidate location, wherein processing the data including identifying the candidate location of an edge includes defining an edge signature between the two materials using a ratio of spectral bands that maximize spectral contrast between the two materials in the data of the image; applying a classifier to the neighboring pixels to determine, based on material changes, if the neighboring pixels are correlated to two different materials with respect to the candidate location, providing a modifier for a spatio-spectral mask; applying the spatio-spectral mask using the modifier to accept or reject the candidate location as an edge; and generating an image to a device, the candidate location in the image correlated to the application of the spatio-spectral mask using the modifier, wherein applying the spatio-spectral mask using the modifier includes using the modifier in an indicator matrix, each element of the indicator matrix correlated to a comparison of a difference of the spatio-spectral mask and the edge signature for a respective neighborhood of the candidate location with respect to a product of a respective modifier and a tolerance parameter.
