HOG object detection with C#

I need a program that runs on C # in the local binary pattern object detection method. Ready libraries should not take part in the project. For example EmguCV, [login to view URL] etc. All calculations and training libraries, completely written by hand. Classification with Adaboost. No console application. It will be a form application. After the training is done, the image for the test will be selected from the form and the object on the picture will be tested. Face detection can be done. For me the calculation stages are important. You can ask if there are parts that are not understood.
