Pelvic bone tumor segmentation fusion algorithm based on fully convolutional neural network and conditional random field.

• Current machine learning algorithms for pelvic bone tumor image segmentation have limited accuracy. • Our proposed algorithm combines a fully convolutional neural network and a conditional random field to achieve more accurate segmentation of pelvic bone tumor images. • FCNN-4s is used to improve the precision and convergence speed of pelvic bone tumor segmentation. • FCNN-4s adopts operations like Crop and Fuse, padding, ReLU activation, and SoftMax loss with optimized hyperparameters for better performance. • Our algorithm demonstrated an improvement of 6.69% in terms of the Dice coefficient compared to other algorithms, with an average enhancement of 9.33% Pelvic bone tumors represent a harmful orthopedic condition, encompassing both benign and malignant forms. Addressing the issue of limited accuracy in current machine learning algorithms for bone tumor image segmentation, we have developed an enhanced bone tumor image segmentation algorithm. This algorithm is built upon an improved full convolutional neural network, incorporating both the fully convolutional neural network (FCNN-4s) and a conditional random field (CRF) to achieve more precise segmentation. The enhanced fully convolutional neural network (FCNN-4s) was employed to conduct initial segmentation on preprocessed images. Following each convolutional layer, batch normalization layers were introduced to expedite network training convergence and enhance the accuracy of the trained model. Subsequently, a fully connected conditional random field (CRF) was integrated to fine-tune the segmentation results, refining the boundaries of pelvic bone tumors and achieving high-quality segmentation. The experimental outcomes demonstrate a significant enhancement in segmentation accuracy and stability when compared to the conventional convolutional neural network bone tumor image segmentation algorithm. The algorithm achieves an average Dice coefficient of 93.31 %, indicating superior performance in real-time operations. In contrast to the conventional convolutional neural network segmentation algorithm, the algorithm presented in this paper boasts a more intricate structure, proficiently addressing issues of over-segmentation and under-segmentation in pelvic bone tumor segmentation. This segmentation model exhibits superior real-time performance, robust stability, and is capable of achieving heightened segmentation accuracy. [ABSTRACT FROM AUTHOR]
