we extend the region-based global contrast visual saliency detection model, and use the saliency map produced by this model as the initial input.

as the keypoints of the scale space mean that there is some important information in the local range of this keypoint, so we propose a method to generate a saliency map using the scale and location information of the keypoints.

由于尺度空间关键点表征该点局部范围存在某一重要的图像信息，因此本文提出了利用关键点尺度及位置信息生成显著图方法。
