Uterine fibroids are the most common pelvic tumors in females. Ultrasonic image segmentation is a difficult problem due to speckle noise, low contrast, and local changes of intensity.Intensity-based methods do not perform particularly well on ultrasound images. However, it has been previously the speckle noise is removed by the Discrete Wavelet Transform (DWT). Then these images respond well to local Phase-Based Level Set methods (PBLS)which are theoretically intensity invariant. The proposed approach performances are evaluated in terms of accuracy, specificity and sensitivity.

Abstract


Uterine fibroids are the most common pelvic tumors in females. Ultrasonic image segmentation is a difficult problem due to speckle noise, low contrast, and local changes of intensity.Intensity-based methods do not perform particularly well on ultrasound images. However, it has been previously the speckle noise is removed by the Discrete Wavelet Transform (DWT). Then these images respond well to local Phase-Based Level Set methods (PBLS)which are theoretically intensity invariant. The proposed approach performances are evaluated in terms of accuracy, specificity and sensitivity.
