i have made cbir system in matlab , have used similarity measurement euclidean distance. using each query image retrieve top 20 images. i have used wang dataset testing system. contains 10 classes(like african people, buses, roses etc.) each containing 100 images.(1000 images in total). my method: 1. using correlogram, co-occurence matrix(ccm) , difference between pixel scan pattern(dbpsp) constructing vector(64+196+28=288 dimensions respectively). each of 1000 db image have vector constructed beforehand. now query image comes , construct it's vector too(228 dimensions again). i use euclidean distance similarity , sort db image vectors in descending order of euclid distance. top 20 results shown. in 20 can have tp or fp. for single query image can calculate precision , recall , plot pr-curve using link . how can same whole class? my approach: each image belonging class find top 20 images , it's respective tp(true positives) , fp (false positive). ...

it seems ccstring deprecated in cocos2d-x v3.5. should use instead? also, reason deprecation? short answer: use std::string instead. the entire codebase moving toward using standard library (stl, std:: namespace) makes sense new c++11 features. you can continue use ccstring anywhere using ccarray , ccdictionary. these deprecated, of course, should move using std::string. valuemap, , valuevector replacements ccarray , ccdictionary based on stl std::map , std::vector , contain value objects. value can hold std::string, int, float, bool, valuemap/valuevector allow nested containers.

is there way add additional attributes laravel error messages? witherrors method seems allow setting either string message or messagebag (which comes validator) response errors can accessed in templates (from session). is there way somehow customise messages? being able add/set attributes (like color, priority, source, icon etc.) message , retrieve them in template allow me "decide" how present it. i guess 1 way using named message bags, that's not convenient. in fact way "group" messages , have walk through every possible group in template anyway. any ideas? thank you validation error messages key-value pairs "standard" properties cannot applied easily. it possible customize error messages text. if using form request validation use function messages() sometimes adding custom variables view, example myerror know display differently.

i use function in three.js 69 function point3dtoscreen2d(point3d,camera){ var p = point3d.clone(); var vector = p.project(camera); vector.x = (vector.x + 1) / 2 * window.innerwidth; vector.y = -(vector.y - 1) / 2 * window.innerheight; return vector; } it works fine when keep scene still. when rotate scene made mistake , return wrong position in screen. it occurs when rotate how 180 degrees.it shoudn't have position in screen showed. i set position var tmpv=point3dtoscreen2d(new three.vector3(-67,1033,-2500),camera); in update , show css3d.and when rotate 180 degrees less 360 , point shows in screen again.obviously it's wrong position can telled scene , haven't rotate 360 degrees. i know little matrix ,so don't know how project works. here source of project in three.js: project: function () { var matrix; return function ( camera ) { if ( matrix === undefined ) matrix = new three.matrix4(); ...

i have third party library kind of shared memory (between processes) implementation preset number of memory buffers. processes divided reading , writing . this library gives file-descriptor each process. i wanted test functionality, using code sample (single process divided reading , writing functionality) provided library. code sample worked, wanted understand file descriptors , how work. this basic code sample (reduced , commented me) (uses 4 shared buffers ): int fd1, fd2; // 2 file descriptors, fd1 writing , fd2 reading sharedmemory_getdescriptor(&fd1, options1); // options1 tells library fd1 used writing data sharedmemory_getdescriptor(&fd2, options2); // options2 tells library fd2 used reading data fd_set readset, writeset; // fd_sets later select commands // empty sets fd_zero(&readset); fd_zero(&writeset); // find out whether writer may write fd_set(fd1, &writeset); fd_set(fd2, &readset); // why has 1 set?? // test sets "ready r...

i need clear $scope values while performing operations. for eg: if click "signout" button redirect "signin" page, $scope or $rootscope values in session should cleared. how can achieve this? you can following: $rootscope = $rootscope.$new(true); $scope = $scope.$new(true); the function $new creating new scope inheriting variables parent. true prevents inheritance. but not correct approach, because if use thing above, should bootstrap controllers functions manually , recreating tree of scopes. this might useful though, idea store initialized data stored in variables , then, when assigned copied displayed variables. the correct solution clear manually every property in each scope on logout event this: logout event: $rootscope.$emit("logout"); catching event: $rootscope.$on("logout", function(){ $rootscope.mydata = undefined; }); or suggested in comments, use service , cleaned.
