i confused how use opencv findhomography method compute optimal transformation. the way use follows: cv::mat h = cv::findhomography(src, dst, cv_ransac, 5.f); no matter how many times run it, same transformation matrix. thought ransac supposed randomly select subset of points fitting, why return same transformation matrix everytime? related random number initialization? how can make behaviour random? secondly, how can tune number of ransac iterations in setup? number of iterations based on inlier ratios , things that. findhomography give optimal transformation. real question meaning of optimal . for example, ransac you'll have model minimum reprojection error, while lmeds you'll have model minimum median error. you can modify default behavior by: changing number of iteration of ransac setting maxiters (max number allowed 2000) decreasing (increasing) ransacreprojthreshold used validate inliers , outliers (usually between 1 , 10). regard...

i want inject httpcontext controller's constructor. knows how configure in configureservices()? thanks injecting httpcontext directly in dependencies not recommended approach. instead, should use ihttpcontextaccessor : public class mycomponent : imycomponent { private readonly ihttpcontextaccessor contextaccessor; public mycomponent(ihttpcontextaccessor contextaccessor) { this.contextaccessor = contextaccessor; } public string getdatafromsession() { return contextaccessor.httpcontext.session.getstring(*key*); } } that said, it's not needed in controller, can retrieve current httpcontext using context property. of course, due way controllers created, property unavailable when instantiate controller, don't try access constructor. in case, try refactor code avoid accessing httpcontext there or use ihttpcontextaccessor replacement.

i developing android app doctors. somewhere in app, doctor can choose view of appointments 1 given month. the thing 1 specific patient may have more 1 appointment doctor in month, maybe 2, 3 or more. , let's doctor doesn't have 1 patient, lots of them. so, have let's 10 different patients, each of them having 3 different appointments given month doctor. sums 10x3=30 appointments particular month. i thought of managing appointments using listview (or recyclerview ) sort of custom item views . thing don't think that's going optimal way present ordered, important data doctor. nor going visually appealing (should appalling?). maybe there kind of android ui component helps me , missing it. if doing such app, use listview patients , times of appointment @ each patient view. doctor should tap patient view appointments in detail.

hopefully newbie question. so if have kind of long set of selects in sql , couple of sub-selects within clause, i'm less satisfied formatting in view designer, appears way display/show views after saved. so, in short, there way directly edit views within ssms, , have views retain formatting in code? i.e.; select case /*comment */ when = 5 b = 2 else b = 4 /* why b 4 */ end field_1, dt field_2,... get's mashed up select case /*comment */ when = 5 b = 2 else b = 4 /* why b 4 */ end field_1, dt field_2,... or along lines. are using query designer? instead, use ssms query window. ssms object explorer, right-click on view , select script view as-->alter to-->new query editor window. format view source in query window , run script change view. formatting preserved.

trying write java code single row battleship style game, , when tried convert array arraylist, game started returning "miss" no matter what. public class simpledotcomgame { public static void main(string[] args) { int numofguess = 0; scanner sc = new scanner(system.in); simpledotcom dot = new simpledotcom(); int rannum = (int) (math.random() * 5); arraylist<integer> locations = new arraylist<integer>(); locations.add(rannum); locations.add(rannum + 1); locations.add(rannum + 2); dot.setlocationcells(locations); //think you're running // separate program parameters set cells "locations" boolean isalive = true; while (isalive == true) { system.out.println("enter number"); string userguess = sc.next(); string result = dot.checkyourself(userguess); //run program // check if cells hit...

i working on effect game have several (200) stars coming edges of screen, moving towards middle while fading out. i want render each star on own (as it's own object) stars can have randoms speed, fade times, size , position. i'm afraid might effect older phones in performance, change alpha , rendering 200 sprites each frame 20 seconds (i recreate them when fade out). as alternative use larger chunks of stars same sprite (one image) means i'll have sacrifice random effects , stars fade out @ same time, obv won't good. i have no way test on older phones i'll ask here, looping through 200 sprites each frame (small images alter alpha each frame , position)? there alternative doesn't force me give random behaviour of each star? or have bite bullet , render larger images (maybe 3-4 different images several stars in each)? you try flyweight pattern , explanation , tutorial found here . have default model of sprite (in case, star) , draw @ different p...

i in polymer... <dom-module id="logo-standard"> <style> :host { display: block; } </style> <template> <div class="logo-wrap"> <div style="width: {{logowidth}}px;"> awesome logo </div> </template> <script> (function() { polymer({ is: 'logo-standard', properties: { logowidth: { type: string, value: '400' } } }); })(); </script> </dom-module> i.e. dynamically style element using property. is possible? if so... how? this question has been answered me here as of polymer 1.2.0 , can use compound bindings to combine string literals , bindings in single property binding or text content binding like so: <img src$="https://www.example.com/profiles/{{userid}}.jpg"> <span>name: {{lastname}}, {{firstname}}</span> and example <div style$="width: {{logowidth}}px;">...
