| 发明名称 | Systems and methods for classifying objects in digital images captured using mobile devices | ||
| 摘要 | In one embodiment, a method includes receiving a digital image captured by a mobile device; and using a processor of the mobile device: generating a first representation of the digital image, the first representation being characterized by a reduced resolution; generating a first feature vector based on the first representation; comparing the first feature vector to a plurality of reference feature matrices; and classifying an object depicted in the digital image as a member of a particular object class based at least in part on the comparing. | ||

| 主权项 | 1. A method, comprising: receiving a digital image captured by a mobile device; and using a processor of the mobile device: generating a first representation of the digital image, the first representation being characterized by a reduced resolution;generating a first feature vector based on the first representation;comparing the first feature vector to a plurality of reference feature matrices;classifying an object depicted in the digital image as a member of a particular object class based at least in part on the comparing; andbinarizing the digital image based at least in part on one or more of the classifying and a result thereof;wherein the binarizing comprises: determining an object class color scheme;adjusting one or more binarization parameters based on the object class color scheme; andthresholding the digital image using the one or more adjusted binarization parameters. | ||
