Abstract

The invention discloses a quick detection method for a salient object. In the method, wavelet transformation is executed on a to-be-detected image many times, the size and the position of the salient object are determined according to high-frequency band data which is obtained through wavelet transformation, and then, an accurate saliency value is obtained through a center-perimeter histogram algorithm, thus, the salient object is detected accurately. In comparison with the prior art, the method provided by the invention has the benefits of high detection efficiency and accurate localization.
