Activity Forecasting Demo Code:


There are two parts (IOC and OC) to the demo code, which can be used to generate the forecasting distribution over future paths. You can use the IOC code to learn an optimal set of reward parameters. The OC demo allows you to run just the test time inference with a set of reward parameters. Here are images generated by the code. You need to have OpenCV 2.3+ installed to run the programs.
