Saliency detection based on frequency domain combined with spatial domain
saliency detection method for single domain is easy to cause the disadvantage of useful information loss. So a model is proposed by combining global information of the frequency and local information of the spatial to obtain more comprehensive saliency target information. The model is necessary. Through fusing the useful information of two domains
the final saliency detection combines the detail of the local information with the integrity of the global information. This model can not only strengthen saliency regions
but also can suppress non-significant parts in a complex background. Saliency detection which is obtained by the new model are clear and complete
and it can inhibit the background information to highlight the saliency regions. Experiments showed that the proposed model relative to the other single domain model can extract significant target area better. Compared with single domain model
the new model improved 9.5% relatively to spatial domain model
and improved 6.3% relatively to frequency domain model.
