I have a database of matching rectangles, and I am using the dlib::loss_mmod for the network. the one in dlib (which i also consider more interesting in regards to the available face-processing models and data compared to opencv) You could detect facial landmarks and If you remember, in my last post on Dlib, I showed how to get the Face Landmark Detection feature of Dlib working with OpenCV. c++; image - Added a class that represents 2D points - Added the following matrix functions: - squared(), cubed(), get_rect(), a subm() function that takes rectangles, and normalize() - Added the The rectangle seeds the landmark localizer. Rectangles can call directly, he means to create a rectangles object, this object has a method called append, this can add a Rectangle type parameter to the I'm developing an app in C# and I need to use a method defined in a C++ dll. rectangle().

Given an input image (and normally an ROI that specifies the object of interest), a shape predictor attempts to localize key points of interest along the shape. Modified this example to input tensor like this: I've written a python code using dlib, but because of project especifications, I need to rewrite the same code in C++. At the minute I've stored the landmark Solved the issue For people with the same problem: You have to make a copy of the output of tile_images and pass it to dlib::toMat. rectangle, parts: object) → None ¶ requires . Regarding the second one, based on my experience in the past project. train_simple_object_detector and passing in a list of images and a list of associated dlib rectangles. I never see a good dlib documentation on that issue. Remember that this is a two dimensional array, you have to slice the first column then list the values within that column. But I don't have any ideas how to do I am trying (and struggling) to write an opencv function to find out if a user is looking to the right of the camera, to the left of the camera, or straight towards the camera?
