Here is shown that both cv::Mat and Standard Library Containers work under memory recycling. We found that using std:queue as buffer for OpenCV Mat, memory requirements depends on size of the queue. We conclude that containers like std::queue can be used effectively as buffer for OpenCV Mats.
A single lock, multiple producer/consumer (MPMC) thread safe queue with wait/timeout Pop. It also provides tools to manage elements like
cv::Mat and an interface for custom OnPush event handler.
To display an OpenCV image or video into your own MFC interface in Visual C++ you can use GDI's function but keep care of details.
Viene presentata una classe la lettura ultra veloce di un file bitmap in C++. La versione originale a cura di Benjamin Kalytta è stata modificata da PkLab introducendo, tra l'altro, il riutilizzo della memoria.
This page describes how to use Image::FromFile methods to read image form file and howto gain fast access to its pixel using
Bitmap::LockBits in VisualStudio. Example code and performance test are shown. Finally, above performace are compared to C++ native CBitmap class.
Gaussian filter is used for signal processing. It Is a low band pass filter usefull to remove high fequency noise (Smoothing). This page shows a 2D recursive implementation as explained by T.Youg, Lucas J, van Vliet
OpenCV means Open Source Computer Vision Library. It is software library that implement many popular Image Processing, Computer Vision and machine learning algorithms.
Viene descritta la porta parallela (centronics), la sua gestione e programmazione anche come porta di I/O. Viene presentato un semplice software di comunicazione tramite porta parallela
