Embodiment Construction
[0072] The technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0073] see Figure 1-8 , the present invention provides a technical solution: a calculation method for automatic scaling of content-sensitive images with salient depth-of-field features, including S0 boundary-type saliency depth-of-field calculation, A0 depth-of-field estimation algorithm and A8 deformation calculation of non-salient regions, S0 boundary type Salient depth of field calculation, the steps and calculation are as follows:
