Abstract
Methods and apparatus are disclosed related to classifying illuminated objects. A computing device can receive a sequence of images including first and second images. The first image can be of an environment of a vehicle taken at a first time. The second image can be of the environment of the vehicle taken at a second time. The vehicle can include a light source that illuminates a portion of the environment. The first and second times can differ. The computing device can detect an object having a first size and a first brightness in the first image. The computing device can detect the object having a second size and a second brightness in the second image. The computing device can classify the object based on a brightness difference between the first brightness and second brightness and a size difference between the first size and second size.
