Multispectral detection of personal attributes for video surveillance

摘要

Techniques, systems, and articles of manufacture for multispectral detection of attributes for video surveillance. A method includes generating one or more training sets of one or more multispectral images, generating a group of one or more multispectral box features, using the one or more training sets to select one or more of the one or more multispectral box features to generate a multispectral attribute detector, and using the multispectral attribute detector to identify a location of an attribute in video surveillance, wherein using the multispectral attribute detector comprises, for one or more locations on each spectral band level of the multispectral image, applying the multispectral attribute detector and producing an output indicating attribute detection or an output indicating no attribute detection, and wherein the attribute corresponds to the multispectral attribute detector.

1. A method comprising:
generating one or more training sets of one or more multispectral images, wherein said generating one or more training sets comprises generating a positive training set by:
collecting one or more multispectral images of a given attribute for which a multispectral attribute detector is to be trained;selecting one or more rectangular regions in the one or more collected multispectral images that correspond to the given attribute; andrescaling the one or more selected regions to correspond to a desired multispectral attribute detector size; generating a group of one or more multispectral box features; using the one or more training sets to select one or more of the one or more multispectral box features to generate a multispectral attribute detector; and using the multispectral attribute detector to identify a location of an attribute in video surveillance, wherein using the multispectral attribute detector comprises, for one or more locations on each spectral band level of the multispectral image, applying the multispectral attribute detector and producing an output indicating attribute detection or an output indicating no attribute detection, and wherein the attribute corresponds to the multispectral attribute detector.
