Abstract
Disclosed are embodiments for determining detection certainty in a cascade classifier (). A first sequence () of detection stages () determines whether an image () is associated with a rare object. Each of the stages () rejects the image () when the image () is unassociated with the rare object and propagates the image () to a next stage () when the image () is unrejected. A second sequence () of detection stages () is configured for post-processing operation. If the image () is unrejected in a final stage () of the first sequence (), the second sequence () determines whether the image () is associated with the rare object. Each of the stages () propagates the image to a next stage (), recording a rejection when the image () is unassociated with the rare object. A probability that the image () is associated with the rare object is determined.
