Detailed description

I tested the ssd_mobilenet in Opencv3.3.1 , Furthermore, i want to use another model such as Faster RCNN (Tensorflow).

My question is, I have to convert the model and wight from Tensorflow to Caffe to be able to use in OpenCV or there is another alternative way to use it (.pbtxt 'conf text graph is not provided in a good format which should be readable in OpenCV )?

The second question about the parameters used in Ssdmobilenet inScaleFactor = 0.007843f, meanVal = 127.5. they are somehow not understandable for me, I will really appreciate if someone can explain those valves and how can be chosen, and it should change from model to another?
