1. An apparatus, comprising:
one or more processors configured to:
obtain a source medical image that includes an object of interest and a background area surrounding the object of interest, wherein the object of interest and the background area exhibit a contrast in the source medical image;
determine, from the source medical image, a first plurality of pixels associated with the object of interest and a second plurality of pixels associated with the background area, wherein the first plurality of pixels has respective first pixel values and the second plurality of pixels has respective second pixel values; and
generate a target medical image based on the first plurality of pixels and the second plurality of pixels so as to enhance the contrast between the object of interest and the background area in the target medical image, wherein the one or more processors are configured to enhance the contrast between the object of interest and the background area by adjusting at least the first pixel values of the first plurality of pixels or the second pixel values of the second plurality of pixels.
