Cascaded Object Detection

摘要

Cascaded object detection techniques are described. In one or more implementations, cascaded coarse-to-dense object detection techniques are utilized to detect objects in images. In a first stage, coarse features are extracted from an image, and non-object regions are rejected. Then, in one or more subsequent stages, dense features are extracted from the remaining non-rejected regions of the image to detect one or more objects in the image.

1. A computer-implemented method comprising:
receiving an image; for a first stage:
extracting features from the image;identifying, based on the extracted features, non-object regions of the image which do not include an object;rejecting the non-object regions of the image; for one or more subsequent stages:
extracting additional features from non-rejected regions of the image;identifying, based on the additional extracted features, additional non-object regions of the image;rejecting the additional non-object regions of the image; for a final stage of the one or more subsequent stages, detecting one or more objects in the image based on features extracted in the final stage.
