Methods, apparatuses, and computer program products are provided for identifying a region of interest within a mammogram image. A method may include applying a clustering algorithm to a histogram of the mammogram image to identify a predefined number of threshold values. The method may further include determining a predefined number of seed values based at least in part on the identified threshold values. The method may additionally include generating a kernel image for each of the seed values. The method may also include using the generated kernel images to identify a region of interest including a breast within the mammogram image. Corresponding apparatuses and computer program products are also provided.
