Abstract

The invention provides an image analysis method based on self-adaptive regularization. The image analysis method mainly comprises a self-adaptive regularization method, the application of the self-adaptive regularization to imaging problems and overall energy optimization, and comprises the following processes: the self-adaptive regularization method is used for optimizing compound energy functions generated in image analysis problems, the data fidelity and the regularization degree are automatically balanced according to current data fitting in the process of iterative optimization, a Huber loss function is also required to be used in the data fidelity and regularization items, an efficient convex optimization algorithm based on an alternate direction multiplier algorithm is provided, and by the use of an equivalence relation between the Huber function and a single norm approximation operator, the self-adaptive regularization method is verified in a synthetic or real image through image segmentation, dynamic prediction, image de-noising and other problems; results prove that compared with a conventional image analysis model, a self-adaptive Huber-Huber model applying the method has relatively better robustness and higher efficiency.

Description

technical field [0001] The invention relates to the field of image analysis in computer graphics, in particular to an image analysis method based on adaptive regularization. Background technique [0002] Image analysis based on adaptive regularization is an important research field in digital image processing, and it plays an important role in image processing such as image restoration, image segmentation and image denoising. However, image restoration is an inverse problem from a mathematical point of view, and has a great morbidity, so regularization processing is necessary, and from a statistical point of view, regularization processing is actually a prior information constraint of the image. In addition, the combination of filtering method and regularization technology can well reduce the random noise in the image, the background and the systematic noise of the fringe intensity variation, so that the image output is well optimized. Relevant research results have also be...
