Extracorporeal shock wave lithotripsy (ESWL) is the most effective and common practice for the treatment of renal calculi. After the treatment X-ray or ultrasound images are used to visually estimate the fragmentation of the stone. Unfortunately, up to now, there is not any method for quantitative estimation of the fragmentation level from ultrasound images. Conventional ultrasound image systems acquire...
A segmentation approach based on a Markov random field (MRF) model is an iterative algorithm; it needs many iteration steps to approximate a near optimal solution or gets a non-suitable solution with a few iteration steps. In this paper, we use a genetic algorithm (GA) to improve an unsupervised MRF-based segmentation approach for multi-spectral textured images. The proposed hybrid approach has the...
