摘要

We want to create realistic immersive personal virtual environments using stereo panoramas. We explore methods to adjust the disparity of stereoscopic images to lie within an acceptable range for human viewers and provide a comfortable stereo viewing experience. Peleg et al described a disparity adjusting method which modifies the disparity of selected objects but also the columns including the object. In this paper, we develop a human interactive object-based tool to adjust selectively the horizontal disparity in stereo panoramas. It enhances or reduces the stereo visual effect for selected 2D object regions without changing the disparities of other regions in the image. Our interactive object-selecting tool is based on the mean-shift segmentation method. The object presented in either a left or right image is selected by user's inputting seed points near the desired object boundary, and object contours both in left and right image are automatically found by our object-selecting algorithm. The complete interactive disparity-adjusting tool allows the user to select the object either from manual input using a cursor, or by defining an area with a certain distance range, with the ability to observe the results immediately on an autostereoscopic display or other stereo display.
