Embodiment Construction
[0034] According to the above-mentioned first main purpose, the present invention provides a method for evaluating image fidelity, comprising the following steps:
[0035] A uses the energy function that needs to be evaluated to perform content-dependent size scaling on pre-selected images through the seam carving algorithm.
[0036] B finds the corresponding points in the original image in the latter image.
[0037] C compares the latter image with the original image, and obtains the fidelity evaluation result of the energy function according to the comparison result.
[0038] The content-related scaling of the image in step A is as follows: After selecting the subject content to be retained on the image, using the energy function to be evaluated, the image is scaled to any size based on the subject content through the seam carving algorithm.
[0039] Find the corresponding relationship between the positions of the points on the original image and the subsequent image as des...
