发帖数: 35 | 1 Hi everyone,
I have a series of 2D surfaces over time, and wish to find each pair's
similarities. You may imagine the surface
as a rectangle patch of a sea surface, and wondering how this part of the
sea surface is changed over time, in
terms of a similarity or dissimilarity measure ( a scalar value).
Any suggestions appreciated. Many thanks. |

发帖数: 35 | 5 I've changed my viewpoint and have converted my problem to another one. For
similarities between images there are lots of approaches but accuracy may be
a point. I previously used the idea of simply computing the correlation
coefficients between the two (similar to the matched filter idea, if i am
correct), and it's kind of close. For matrices perhaps can just regard them
as a vector (either by row or by column).
Let me know please if you come to something interesting. thanks. |
