Accurate and efficient medical image segmentation is a critical yet challenging task due to issues like intensity inhomogeneity, poor contrast, noise, and blur. In this paper, we introduce a novel framework that addresses these challenges by leveraging adaptive level set evolution, enhanced with a unique edge indication function. Unlike prior edge-based algorithms, which frequently fail with noisy images and have large computing costs, our method incorporates an improved edge indicator term into the level set architecture, considerably improving performance on degraded images. The efficiency of proposed model depends on the optimization and implementation of proximal alternating direction technique of multipliers ([Formula: see text]). Our findings were validated using qualitative and quantitative methods such as dice coefficient assessment, sensitivity, accuracy, and mean absolute distance (MAD). Experimental findings show that the model successfully detects boundaries of objects within noisy and blurred visual data. The algorithm showed exceptional precision through its average dice coefficient of 0.96 which matched the ground truth data measurement standards. The system runs efficiently for only 0.90 seconds on average as a performance result. The framework achieved standout performance metrics that included 0.9552 accuracy together with 0.8854 sensitivity and 0.0796 MAD. The framework demonstrates robust capabilities in medical image evaluation which makes it an optimistic instrument for advancing the field.
由于存在诸如强度不均匀、对比度差、噪声和模糊等问题,准确而高效的医学图像分割是一项关键但具有挑战性的任务。在本文中,我们介绍了一种新颖的框架,该框架通过利用自适应水平集演化来应对这些挑战,并通过独特的边缘指示函数进行增强。与先前基于边缘的算法不同,那些算法在处理有噪声的图像时经常失败且计算成本高昂,我们的方法将改进的边缘指示项纳入水平集架构,大大提高了在退化图像上的性能。所提出模型的效率取决于近端交替方向乘子法([公式:见原文])的优化和实现。我们的研究结果通过定性和定量方法进行了验证,如骰子系数评估、灵敏度、准确率和平均绝对距离(MAD)。实验结果表明,该模型成功地检测出了有噪声和模糊视觉数据中物体的边界。该算法通过其平均骰子系数0.96显示出卓越的精度,这与地面真值数据测量标准相匹配。作为性能结果,该系统平均仅需0.90秒就能高效运行。该框架实现了出色的性能指标,包括0.9552的准确率、0.8854的灵敏度和0.0796的MAD。该框架在医学图像评估中展示了强大的能力,使其成为推动该领域发展的一个乐观工具。
