摘　　要：提出一种基于参考点的改进的滑动窗目标检测算法.采用不同的分割方法对图像进行分割,使某一分割接近真实目标位置,并将左上角点标定为参考点,然后将分割区域的模型作为底层检测器,并只在参考点上进行模型的训练和测试,以期缩短检测时间.对来自互联网的图片实验表明,在超过60%的检测类别上,改进的方法检测正确率都优于穷举法.An improved gliding window method based on reference point was proposed. A partitioned re- gion was made close to a real location for an object, and the top left comer was set as reference point by separating images into several regions using different separation methods. Then the model of partition re- gion was taken as bottom detector and executed a model test only on the reference point to reduce detec- tion time. The experimental results showed that the detection correctness rate of this method was superior to the method of exhaustion.
