“Each stage of the classifier labels the region defined by the current location of the sliding window as either positive or negative. Positive indicates that an object was found and negative indicates no objects were found. If the label is negative, the classification of this region is complete, and the detector slides the window to the next location. If the label is positive, the classifier passes the region to the next stage. The detector reports an object found at the current window location when the final stage classifies the region as positive.” “Each stage of the classifier labels the region defined by the current location of the sliding window as either positive or negative.

每个阶段的分类器对滑动窗口的当前区域打标签（positive 或 negative）。Positive 意味着检测到了目标，negative 意味着没有检测到目标。如果没有检测到目标则完成当前区域的检测，滑动窗口移动到下一个区域。如果检测结果 positive，则分类器将当前区域传递给下一个阶段继续检测。当所有检测阶段都返回 positive，那么检测器报告在当前位置发现了目标物。 每个阶段的分类器对滑动窗口的当前区域打标签（positive 或 negative）。Positive 意味着检测到了目标，negative 意味着没有检测到目标。如果没有检测到目标则完成当前区域的检测，滑动窗口移动到下一个区域。如果检测结果为 positive，则分类器将当前区域传递给下一个阶段继续进行检测。当所有检测阶段都返回 positive，那么检测器报告在当前位置发现了目标物。
“The stages are designed to reject negative samples as fast as possible. The assumption is that the vast majority of windows do not contain the object of interest. Conversely, true positives are rare and worth taking the time to verify.” “The stages are designed to reject negative samples as fast as possible.
