matlab - CCA for Feature Fusion -

-

in of multi-modal recognition methods, using canonical correlation analysis (cca) fuse 2 input feature vectors single , low dimension one. matlab has code cca is: [a,b,r,u,v] = canoncorr(x,y); see: http://www.mathworks.com/help/stats/canoncorr.html

i wonder how can reach final (fused) feature vector using function. can explain steps or suggest reference, please?

i found out how perform feature fusion using cca. wrote matlab code , shared code in matlab central.

detailed descriptions can found in paper:

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
