Embodiment Construction
[0055] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0056] like figure 1 Shown, the steps of the present invention are:
[0057] (1) Extract image features by SIFT method, perform feature matching, and obtain saliency vectors, and use this as a benchmark to perform spatially consistent deformation.
[0058] (2) Starting from the position of the viewpoint, deform each image frame obtained in step (1), reacquire the feature set, construct a SIFT-based spatial structure matrix, extract rotation, translation, and scaling information, and construct the original motion signal, according to the adaptive The intrinsic modulus function optimization algorithm obtains new motion signals.
[0059] (3) The adaptive motion signal calculated in step (2) is used as a new input signal. According to the feature center algorithm, the motion trend of the original signal is protected as much as possible while the jitter ...
