Abstract

The invention is suitable for the technical field of pattern recognition, and provides a multi-modal image registration method, which comprises the steps of obtaining a first image of a source modal and a second image of a target modal paired with the first image; correcting the intensity of the first image to obtain a first corrected image, so that the intensity of the first corrected image is matched with the intensity distribution of the second image; acquiring a deformation field of the first corrected image registered to a target mode according to the first corrected image and the secondimage; and according to the first image and the deformation field, obtaining a registration image of the first image registered to a target mode. Therefore, the influence of the image intensity characteristics is reduced, and the precision reduction caused by overlarge distance difference between the same object of the to-be-corrected first image and the ideal registration result can be avoided, so that the registration precision is improved.

Description

technical field [0001] The present application belongs to the technical field of pattern recognition, and in particular relates to a method, device, electronic equipment and storage medium for multimodal image registration. Background technique [0002] Image registration is the positioning and transformation of images. For example, in the field of medical image processing, by looking for a spatial transformation, the corresponding points of the two images can be consistent in terms of spatial position and anatomical structure. The purpose of image registration is to compare or fuse images acquired under different conditions for the same object. In the multi-modal image registration scenario, the registration technology for single-modal images cannot adapt to the differences of multi-modal images, resulting in low registration accuracy. Therefore, a registration method for multi-modal images is needed. Contents of the invention [0003] Embodiments of the present applicat...
