14 Cars Identification

20200806

A practical computer vision task is to identify the make and model of a motor vehicle within a photo. The MLHub package cars demonstrates the utility of Computer Vision for the identification of motor vehicles. We use the Comprehensive Cars dataset available for research purposes (Yang et al. 2015). The pre-built model was trained by Jiajun Zha through the Australian National University’s Software Innovation Institute. The pre-built model build code is available from github.

To install and configure the package:

ml install cars
ml configure cars
ml readme cars
ml commands cars

Note that on the first configure a 188MB file is downloaded, which is the pre-built model. This can take some time. It is cached locally so any further configuration simply uses the cached copy.

The package supports a identify command to identify the object (motor vehicle) in an image. The train command will use the tagged images within a folder of tagged to extend the pre-built model with new motor vehicle makes and models.

The source code for this MLHub package is available from gitlab: https://gitlab.com/kayontoga/cars.
