Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Anatomical structures that can deteriorate over time, such as cartilage, can be successfully delineated with voxel-classification approaches in magnetic resonance (MR) images. Hover, segmentation via voxel-classification is a computationally demanding process for high-field MR images with high spatial resolutions. In this study, the whole femoral, tibial, and patellar cartilage compartments in the knee joint re automatically segmented in high-field MR images obtained from Osteoarthritis Initiative using a voxel-classification-driven region-growing algorithm with sample-expand method. Computational complexity of the classification was alleviated via subsampling of the background voxels in the training MR images and selecting a small subset of significant features by taking into consideration systems with limited memory and processing por. Although subsampling of the voxels may lead to a loss of generality of the training models and a decrease in segmentation accuracies, effective subsampling strategies can overcome these problems. Therefore, different subsampling techniques, which involve uniform, Gaussian, vicinity-correlated (VC) sparse, and VC dense subsampling, re used to generate four training models. The segmentation system was experimented using 10 training and 23 testing MR images, and the effects of different training models on segmentation accuracies re investigated. Experimental results shod that the highest mean Dice similarity coefficient (DSC) values for all compartments re obtained when the training models of VC sparse subsampling technique re used. Mean DSC values optimized with this technique re 82.6%, 83.1%, and 72.6% for femoral, tibial, and patellar cartilage compartments, respectively, when mean sensitivities re 79.9%, 84.0%, and 71.5%, and mean specificities re 99.8%, 99.9%, and 99.9%. Voxel-classification-based segmentation suffers from high dimensionality of MR images.Subsampling of voxels and feature selection can reduce complexity of classification.Random voxel subsampling in training data causes poor cartilage segmentation results.Vicinity-correlated subsampling of voxels improves cartilage segmentation accuracies.A small subset of significant features is adequate to segment cartilage compartments.
