Implementations of the present invention involve methods and systems for converting a 2-D image to a stereoscopic 3-D image and displaying the depth of one or more pixels of the 3-D image through an output image of a user interface. The pixels of the output image display the perceived depth of the corresponding 3-D image such that the user may determine the relative depth of the pixels of the image. In addition, one or more x-offset values or z-axis positions may be individually selected such that any pixel of the output image that correspond to the selected values is indicated in the output image. By providing the user with a visualization tool to quickly determine the perceived position of any pixel of a stereoscopic image, the user may confirm the proper alignment of the objects of the image in relation to the image as a whole.
