Patent Document ID: 8538081
Application ID: 13371847

Base Claim:
1. A non-transitory computer-readable medium or media comprising one or more sequences of instructions which, when executed by one or more processors, causes steps to be performed comprising: obtaining a set of image features for a local image window and for a set of neighboring image windows; applying a set of classifiers corresponding to the set of image features to obtain a set of classifier response values for the local image window and the set of neighboring image windows; generating a classification context feature set for the local image window comprising the set of classifier response values for the local image window and the set of neighborhood image windows; constructing a contextual boost feature set comprising the classification context feature set and the set of image features for the local image window and for the set of neighboring image windows; and augmenting the contextual boost feature set by iteratively adding an updated classification context feature set to the contextual boost feature set of an immediately prior iteration until a stop condition is reached.

Claim 7:
7. The non-transitory computer-readable medium or media of claim 1 wherein obtaining a set of image features for a local image window and for a set of neighboring image windows comprises, for each image window of the local image window and of the set of neighboring image windows: generating a context region for the image window comprising at least a portion of the image and formed by selecting a portion or portions of the image that are within a context region area defined relative to the image window; constructing a multi-scale feature comprising: a high-scale feature comprising one or more features extracted from the image window at a high-resolution size; a mid-scale feature comprising a combination of one or more features extracted from the image window at a mid-resolution and one or more features extracted from a set of one or more regions at the mid-resolution, the set of one or more regions being formed from the context region; and a low-scale feature comprising one or more features extracted from a combined image window at a low-resolution size, the combined image window comprising the image window and the context region related to the image window.
