1. A method of performing image segmentation to detect lesions, the method comprising: receiving by circuitry an X-ray image of a region including the lesion; filtering the received image by a median filter to reduce speckle noise present in the received image, and forming a filtered image including a plurality of pixels; clustering each image pixel of the plurality of pixels in the filtered image into one of a lesion region and a background region, to form a clustered image; transforming each pixel included in the clustered image into a neutrosophic domain; determining by the circuitry, the neutrosophic domain of each pixel by computing a three-tuple including a first probability corresponding to the pixel being correctly clustered in the lesion region, a second probability corresponding to the pixel being incorrectly clustered in the lesion region, and a third probability corresponding to the pixel being an indeterminate pixel; iteratively computing by the circuitry, until a stop criterion is satisfied, the first probability, the second probability, and the third probability based on a mean value of pixel intensity of a predetermined window and a homogeneity value; and assigning the indeterminate pixel to one of the lesion region and the background region to segment the X-ray image upon the stopping criterion being satisfied, the assigning being performed based on a degree of pixel indeterminacy.
