How to modify dft function in opencv? -

-

i need modify of variables inside dft function in opencv make suitable application.

  1. where can find dft source code? i've tried c:\opencv243\build\include\opencv2\core.hpp gives me description of dft:

    //! performs forward or inverse 1d or 2d discrete fourier transformation cv_exports_w void dft(inputarray src, outputarray dst, int flags=0, int nonzerorows=0);

  2. what procedure after source code modification? have give different name such dft2()?

  3. where save new function?

i'm using visual studio 2010 , opencv 2.4.3 installed on windows7 (32 bit). please note i'm new opencv , switched matlab. therefore if willing help, grateful if explain clearly.

in matlab right-click on function , see source file (for open source functions only).

thanks

  1. dft function can found in dxt.cpp source file. located in $opencv2.3$\opencv\modules\core\src

  2. if save same function overwrite function , wont able use original function. if want new function change code, if want original functionality save else, dft2 surfice suggest saving more meaningfull dft"whathaveidone"

  3. either create new files etc or save new function dxt.cpp, need create function definitions etc

  4. in order find information opened opencv solution in visual studio , did solution wide search dft

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
