Medical Image Segmentation Using a Combination of Lattice Boltzmann Method and Fuzzy Clustering Based on GPU CUDA Parallel Processing

Abstract

The rapid development of computer technology has had a significant influence on advances in medical science. This development concerns segmenting medical images that can be used to help doctors diagnose patient diseases. The boundary between objects contained in an image is captured using the level set function. The equation of the level set function is solved numerically by combining the Lattice Boltzmann (LBM) method and fuzzy clustering. Parallel processing using a graphical processing unit (GPU) accelerates the execution of the segmentation process. The results showed that image segmentation with a relatively large size could be done quickly. The use of parallel programming with the GPU can accelerate up to 39.22 times compared to the speed of serial programming with the CPU. In addition, the comparisons with other research and benchmark data show consistent results.

[Retracted] Clinical Application of Shock Wave in the Treatment of Avascular Necrosis of the Femoral Head in the Early and Middle Stages

“…Medical image segmentation is the basis of medical image processing and analysis. The solution to this problem not only directly affects the successful application of computer graphics and image technology in medicine but also has important theoretical and practical significance [ 6 , 7 ]. Medical image segmentation is a process of extracting regions of interest, and the segmentation results can provide a reference for subsequent disease diagnosis, treatment plan planning, and treatment effect evaluation.…”

Intelligent road boundary identification method based on image segmentation and edge features

“…In the formula (1), l k , r k respectively represent the driving left and right visual field edges, x represents the road horizontal line, l b 、 r b respectively represent the recognized projection edges, and according to the above road edge model [3][4] , the road boundary line extraction hypothesis can be made to judge the mapping relationship between the boundary lines. The camera projection area of different road boundaries is different.…”
