Multiple Regions Query Strategy - Absolute Locations

 

For each region in the query positioned by absolute location, the query strategy outlined for single region query (Section 4.3) is carried out, without computing the final minimization. These lists are intersected and the best image match minimizes the combined region distance. For example, given the multiple region query: find the image having three regions that best matches tex2html_wrap_inline2127 tex2html_wrap_inline2129 tex2html_wrap_inline2131 , where tex2html_wrap_inline2133 tex2html_wrap_inline2135 tex2html_wrap_inline2137 tex2html_wrap_inline2139 gives the query parameters for query region i, the matches are found as follows:

displaymath2125

The query is processed by intersecting the query region lists to obtain the list of candidate images. The best match minimizes the weighted sum of the region distances between the query and target image.
