Embodiment Construction
[0017] The technical problems involved in the technical solution of the present invention will be described below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.
[0018] Such as figure 1 It shows that the present invention proposes a method for on-orbit evaluation of remote sensing image change detection performance, which method includes the following steps:
[0019] Step S1: Multi-temporal salient region extraction uses the sign function of the discrete cosine transform of image grayscale as the saliency metric, first extracts salient regions on the current remote sensing image and historical remote sensing images, and then takes the union of the salient regions as a multi-temporal Salient regions of the phase image. The specific process of extracting the multi-temporal salient region is as follows:
