2020-07-09 02:56:51 -0600 | marked best answer | Android dnn in native C++ Hello, i succesfully linked opencv to my android c++ native app.. now I encountered a problem where i cannot read my models (ex. YOLO) I pasted them here: /storage/emulated/0/DCIM/ <model> but when running I see that the models cannot be found/read. The tutorial on the opencv page is for java implementation, I would like to implement something similar but using native C++. What I have tried:
Has someone encountered the same issue? Or has some tips? Thaaaanks! |

2019-02-22 07:02:31 -0600 | marked best answer | imshow data types? hello! i am havind a problem with the imshow function, according to the documentation it supports Mat of different types than CV_8U imshow_doc, i have been using it on other opencv versions and it works (example opencv 3.4.1).. The Mat that i want to show is CV_64F type, i tried also with CV_16U but i get the same assertion error, i checked the source file: OpenCV(4.0.0) c:\build\master_winpack-build-win64-vc15\opencv\modules\highgui\src\window_w32.cpp:1230: error: (-215:Assertion failed) dst.data == (uchar*)dst_ptr in function 'cvShowImage' and my temporary solution would be to comment that assertion but i am not sure if that would bring other problems. I see in the assertion that it is expecting a uchar data.. maybe thats why it gets error with other types?? Has someone experienced something similar? or has any ideas? thanks! |

I finished the first stage and while implementing the second, the outputs of the network are a bit weird: Input Data: I: 1 C: 3 H: 24 W: 24 Scores Data: I: 1 C: 2 H: 299777088 W: 1 Regression Data: I: 1 C: 3 H: 309665792 W: 1 Rotate Data: I: 1 C: 3 H: 299780800 W: 1 The channels size of each output is correct, but the H,W are confusing me. I don't know if this has to be with the case that the model is the same for all the three networks?. Or maybe is an overflow issue? I tested it just forwarding a simple image with the secont network "PCN-2.prototxt" the output is similar.. has someone experienced something like this? thanks! |
