You could use some of the samples and models already available in the OpenVINO™ toolkit, it really depends what your object is and what you are trying to detect. There are also some samples that let you use a USB cam as your input, for example the Object Detection C++ Sample SSD, or if you prefer Python* here.
You can take a look at the Inference Engine Samples available for more sample code. Hope this helps!
