<table border=1> <tr> <th>one</th> </tr> <tr> <td>1</td> </tr> </table> draws table bit wider word "one", , it's ok. <table border=1> <tr> <th>one</th> </tr> <tr> <td style='padding:0 0 0 0'> <input style='width:100%' value='1'> </td> </tr> </table> draws table 4 times wider needed. please advise how make width of input equal 100% of non-stretched td without assigning width of td itself? you can add size attribute input. example: <table border=1> <tr> <th>one</th> </tr> <tr> <td style='padding:0 0 0 0'> <input size='1' value='1'> </td> </tr> </table>

i have xts object want aggregate data--while keeping dates. wln = apply(dln, 2, to.weekly) > head(wln) aapl gspc vix [1,] -0.05602066 -0.0252409007 0.01903172 [2,] -0.03609222 -0.0111470571 0.13182832 i tried using index convert dates, no avail. as pascal commented , can use apply.weekly aggregate returns (i use period.apply below, since general solution). aggregation function use depend on how returns calculated. require(xts) set.seed(21) x <- xts(matrix(rnorm(60, 0, 0.01), ncol=2), sys.date()-30:1) # weekly endpoints wep <- endpoints(x, "weeks") # log returns period.apply(x, wep, colsums) # arithmetic returns period.apply(x, wep, function(x) apply(1+x,2,prod)-1)

i have built opencv 3.0 alpha version source support cuda , tbb. now, want feature detection , feature matching using surf algorithm. surffeaturedetector present in include file opencv2/nonfree/features2d.hpp & opencv2/nonfree/features2d.hpp but module nonfree missing in version of opencv. tried checking opencv forums @ answers.opencv.org site under construction. how use non free modules? with opencv3.0, surf/sift , other things have been moved seperate opencv_contrib repo . you have download that, add main opencv cmake settings (please @ readme there), , rerun cmake/make. then: #include "opencv2/xfeatures2d.hpp" ... ptr<sift> sift = cv::xfeatures2d::sift::create(...); sift->detect(...);

by accident tried estimating relative position of image (don't ask). expect result of 0 translation , 0 rotation. surprisingly, non-zero translation result. in fact rather significant result: .0825 -0.0825 . in essence code follows: cv::point2d pp(u0, v0); cv::mat r, t, mask; cv::mat e = cv::findessentialmat(points1, points2, focal, pp, cv::ransac, 0.999, 1.0, mask); cv::recoverpose(e, points1, points2, r, t); in above code, t != 0. question is: non-zero result recoverpose valid when points1 , points2 identical? if so, why? from decomposeessentialmat documentation: "by decomposing e, can direction of translation" and translation vector constructed in such way norm of translation equal 1.
