C++/OpenCV - How to index pictures for image retrieval? (and find the best image) -


i use bow flann in order index pictures inside database.(for cbir project)

what did :

  1. loop on ma database in order compute descriptors of each pictures.
  2. clustering descriptors using k-mean
  3. extraction of bowdescriptors (visual words) in order have big histogram features
  4. use flann index compute index in each pictures

code: 

// create flann lsh index cv::flann::index flannindex(this->descdescriptorbow, cv::flann::lshindexparams(12, 20, 2), cvflann::flann_dist_hamming);  cv::mat results, dists;  int k=2; // find 2 nearest neighbors  // search (nearest neighbor) flannindex.knnsearch(responsehist, results, dists, k, cv::flann::searchparams() );

descriptorbow contains bowfeatures of database. responsehist constains bowfeature of picture want eval.

now, have in order see best matching picture ?

can me ?

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
