c# - Opencv: Working with 16bit image, Uint16 -


i have 12bit image want work in opencv, such detecting blobs etc.

the image uint16 array. , want convert opencv mat or iplimage. need inorder threshold , detect blobs.

what im doing convert ushort array bitmap, , mat using opencv extensions, see below.

ushort[,] red = new ushort  [480,640]; //grab image in ushort array //..  bmpred = u16arraytobitmap(red);  mat redmat = new mat();  redmat = opencvsharp.extensions.bitmapconverter.tomat(bmpred);

now redmat, mat image u8c4, understand 4 chanel unsigned 8 bit. wont work me, because want use of 12 bits!

is possible convert ushort array or bitmap 16bit grayscale mat or iplimage?

thanks!

you can use mat constructor directly:

var mat = new mat(red.getlength(0), red.getlength(1), mattype.cv_16uc1, red);

or use matofushort:

var mat = new matofushort(red.getlength(0), red.getlength(1), red);

note mat using pointer red array. clone mat if want use copy:

var clone = mat.clone();

for more information check mat - basic image container opencv documentation page , opencvsharp wiki.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

How to understand 2 main() functions after using uftrace to profile the C++ program? -

i trying uftrace profile following simple c++ program: #include <iostream> class { public: a() {std::cout << "a created" << std::endl;} ~a() {std::cout << "a destroyed" << std::endl;} }; int main() { a; return 0; } the profile result this: # uftrace a.out created destroyed # duration tid function 2.026 [ 4828] | __cxa_atexit(); [ 4828] | main() { [ 4828] | __static_initialization_and_destruction_0() { 89.397 [ 4828] | std::ios_base::init::init(); 0.768 [ 4828] | __cxa_atexit(); 93.029 [ 4828] | } /* __static_initialization_and_destruction_0 */ 94.425 [ 4828] | } /* main */ [ 4828] | main() { [ 4828] | a::a() { 11.104 [ 4828] | std::operator <<(); 10.825 [ 4828] | std::basic_ostream::operator <<(); 24.514 [ 4828] | } /* a::a */ [ 4828] | a::~a() { 0.978 [ 4828] | ...

android - Unable to generate FCM token from dynamically instantiated Firebase -

our business logic requires instantiate firebase during runtime. fetch firebase credentials (app id, api key etc.) default firebase location after knowing user's public key , create firebase instance using credentials. this means there 2 firebase instances used within app: the default "index" firebase gives credentials second the actual firebase intend use point forward the second firebase initialised this: firebaseapp app = firebaseapp.initializeapp(<context>, <options>, <app_label>); our problem traditional method of retrieving fcm token using firebaseinstanceidservice , ontokenrefresh() fails since ontokenrefresh() method called first firebase instance. directly calling string token = firebaseinstanceid.getinstance(app).gettoken(); returns null never ready when called. have tried polling test if token generated @ point. no luck. how can generate fcm token reliably firebase instance instantiated during runtime? i...
