c++ - estimate 2D transformation between two set of points using Ransac -

-

as know, opencv uses ransac in order solve problem of findhomograph , return useful parameters homograph_mask. however, if want estimate 2d transformation means affine matrix, there way use same methodlogy of findhomography uses ransac , return mask ?

estimaterigidtransform use ransac internally, though parameters fixed @ moment - see code here - https://github.com/opencv/opencv/blob/master/modules/video/src/lkpyramid.cpp

cv::mat cv::estimaterigidtransform( inputarray src1, inputarray src2, bool fullaffine ) {     const int ransac_max_iters = 500;     const int ransac_size0 = 3;     const double ransac_good_ratio = 0.5;      // ...      // ransac stuff:     // 1. find consensus     for( k = 0; k < ransac_max_iters; k++ )     {         int idx[ransac_size0];         point2f a[ransac_size0];         point2f b[ransac_size0];          // choose random 3 non-complanar points & b         for( = 0; < ransac_size0; i++ )         {             for( k1 = 0; k1 < ransac_max_iters; k1++ )             {

javascript - Chart.js (Radar Chart) different scaleLineColor for each scaleLine -

i try , create radar chart using chart.js has various colours each scaleline, or coloured between scalelines. wondering if possible? from: to: i have working graph, though there doesn't seem method change individual scale lines. kind regards leigh you can extend radar chart type this, so chart.types.radar.extend({ name: "radaralt", initialize: function (data) { chart.types.radar.prototype.initialize.apply(this, arguments); var originalscaledraw = this.scale.draw; var ctx = this.chart.ctx; this.scale.draw = function () { var linewidth = this.linewidth; // bypasses line drawing in originalscaledraw this.linewidth = linewidth; originalscaledraw.apply(this, arguments); ctx.linewidth = this.linewidth; var scale = this; // draw chart.helpers.each(scale.ylabels, function (label, index) { // color of ...

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
