Problems solved by technology

However, the current neural membrane system is a two-dimensional graph structure, in which neurons can only exchange information with connected neurons, and cannot use a hierarchical structure for calculations and temporarily store intermediate calculation results, which also limits the neural membrane system in hippocampus segmentation. application in

Abstract

The invention provides an MRI (Magnetic Resonance Imaging) hippocampus segmentation method and system based on a hypergraph numerical neural P system. The method comprises the following steps: acquiring an MR image to be segmented; inputting the MR image to be segmented into the hypergraph-based numerical neural P system to obtain a hippocampus segmentation result; wherein the supergraph-based numerical neural membrane system comprises superneurons, and an encoder and a decoder consisting of a plurality of basic neurons, the encoder and the decoder are used for learning up-sampling and down-sampling features of the hippocampus in the MR image, and the superneurons are used for jumping and series fusion between the encoder and the decoder. The high precision of the deep learning model in semantic segmentation is combined with the good parallelism and robustness of the membrane system, and the performance of hippocampus segmentation is improved.

Description

technical field [0001] The invention belongs to the technical field of image segmentation, and in particular relates to an MRI hippocampus segmentation method and system based on a hypergraph numerical neural membrane system. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The hippocampus is an important brain structure that affects human cognition, memory and emotion. Accurate segmentation of the hippocampus can help identify early atrophy of the hippocampus, which helps doctors predict and diagnose various neurological diseases, such as Alzheimer's disease ( AD), epilepsy, and schizophrenia, and developing a treatment plan. However, manual delineation by radiologists takes a lot of time and is often not repeatable. Therefore, an accurate and efficient automatic hippocampal segmentation method is needed. However, the following problems m...
