The Research of Bottom-Up and Top-Down Combination Visual Attention Calculative Method

A new bottom-up and top-down combination visual attention calculative method is proposed in paper. The method proposed is focus on the improvement of top-down guidance. The total visual attention process is divided into the process of bottom-up visual information extraction and top-down visual attention guiding. The construction and calculate method of visual attention guiding layer is presented in paper, it can automatic calculate the key feature of the target based on current task condition, and guide the process of bottom-up visual information extraction.
