DEVICE FOR MANAGING A VISUAL SALIENCY MODEL AND CONTROL METHOD THEREOF

A method for controlling a device to manage a visual saliency model can include receiving, via a processor in the device, a center bias map and a saliency density ground-truth map for an image; normalizing values of the saliency density ground-truth map to generate a normalized density ground-truth map; and comparing values of the normalized density ground-truth map to a predefined threshold value to generate an enhanced ground-truth map. The method can further include subtracting the enhanced ground-truth map from the center bias map to generate a negative candidates map; normalizing values of the negative candidates map to generate a normalized candidates map; and performing a sampling process on the normalized candidates map to generate a negative point map. Also, the method includes applying a filter function to the negative point map to generate a negative density map.
