A system, method, and computer program product are provided for displaying a combined image based on a cost function. In use, two or more source images are loaded and a first blend weight is initiated associated with the two or more source images. Next, a first combined image from the two or more source images and a cost function for the first combined image is computed. It is determined whether the cost function is substantially minimized, wherein if the cost function is not substantially minimized, the first blend weight is updated to substantially minimize the cost function, the first combined image is updated based on the updated first blend weight, and the user interface element associated with the updated first combined image is updated. A display then displays the first combined image based on the first blend weight and a user interface element associated with the first combined image. Additional systems, methods, and computer program products are also presented.
