TECHNIQUES FOR IMPROVING STEREO BLOCK MATCHING WITH THE PYRAMID METHOD

摘要

Techniques to determine a search range for a stereo based matching pyramid. A first disparity estimation value for a first level in a stereo based matching pyramid based on an image may be received. A search range for a second level may be determined using the first disparity estimation value. The search range based on a pyramid level of a second level may be increased. The search range may be increased based on a pyramid level of the second level. A second disparity estimation value may be selected from the search area for the second level. A depth map for the second level may be determined based on the second disparity estimation value. Other embodiments are described and claimed.

1. An article of manufacture comprising a storage medium containing instructions that when executed cause a system to:
receive a first disparity estimation value for a first level in a stereo based matching pyramid based on an image; determine a search range for a second level based on the first disparity estimation value; increase the search range based on a pyramid level of the second level; and select a second disparity estimation value from the search range for the second level.
