Abstract
The present disclosures relates generally to image signal processing and encoding signal within imagery.
Claims20
A method comprising:
- obtaining data representing optically captured imagery, the optically captured imagery depicting packaging or a label including an encoded signal, the encoded signal including a synchronization signal that is detectable in a transform domain;
- generating a feature set of the data representing the optically captured imagery, the feature set representing the optically captured imagery in a spatial domain;
- employing a classifier to predict the presence of the synchronization signal in a transform domain from the feature set in the spatial domain.
An apparatus comprising:
- memory for buffering image data, the image data having been captured with a camera and depicting product packaging or a product label;
- one or more processors programmed for:
- generating a spatial domain feature set representation of a portion of image data;
- evaluating the spatial domain feature set with a classifier to predict whether the portion of image data includes a transform domain encoded signal.
1 more element
A non-transitory computer readable medium comprising instructions stored therein, said instructions configure one or more processors for:
- obtaining data representing optically captured imagery, the optically captured imagery depicting packaging or labeling including an encoded signal, the encoded signal including a synchronization signal that is detectable in a transform domain;
- generating a feature set of the data representing the optically captured imagery, the feature set representing the optically captured imagery in a spatial domain;
- predicting the presence of the synchronization signal in a transform domain from the feature set in the spatial domain, said predicting utilizing a classifier.
