Abstract

The invention relates to the technical field of computer vision, and discloses an MR brain tumor image instance segmentation method, device and equipment and a storage medium, that is, on the basis of an existing Mask RCNN instance segmentation model and a feature pyramid network (FPN), a bottom-up path enhancement Bottom-up Path Augmentation is added on the FPN, so that the segmentation efficiency is improved. Then, a convolutional layer attention mechanism CBAM is introduced into an up-sampling path of a Top-down path and a down-sampling path of a Bottom-up Path Augmentation of a top-down path of the FPN respectively, so that the problem that the shape and size of the tumor are changed due to individual difference and time change can be better solved, and meanwhile, a low-resolution feature map and a high-resolution feature map are fused; according to the method, the detection effect of a small target can be effectively improved, the omission ratio of small-size tumors is reduced, help is provided for early screening of the tumors, and therefore the segmentation performance is improved, and good universality is achieved.

Description

technical field [0001] The invention belongs to the technical field of computer vision, and in particular relates to an MR brain tumor image instance segmentation method, device, equipment and storage medium. Background technique [0002] Magnetic Resonance Imaging (MRI) is a non-invasive imaging technique that allows the noninvasive characterization of mesoscopic features of organs or tumors. MRI technology can provide good spatial anatomical information, has good soft tissue contrast detection ability, and can obtain tomographic scans in any orientation without reconstruction. The obtained multi-sequence and multi-modal imaging can provide rich image information for clarifying the nature of lesions, helping Physicians and researchers understand the pathophysiology of brain diseases to aid in imaging diagnosis, prognosis, and oncology treatment. In the clinical environment, accurate detection and segmentation of lesions is of great significance for patient condition assess...
