Abstract: A method includes obtaining a reference image and a target image each representing an environment containing moving features and static features. The method also includes determining an object mask configured to mask out the moving features and preserves the static features in the target image. The method additionally includes determining, based on motion parallax between the reference image and the target image, a static depth image representing depth values of the static features in the target image.

The model is trained to generate the dynamic depth image by determining depth values of at least the moving features based on the target image, the object mask, and the static depth image.

Abstract: An oil separator includes a container and a filter assembly. The filter assembly can include a casing, a valve guide, and a valve body. First and second chambers can be defined by a lower casing body. The valve guide can guide the valve body's movement between first and second positions in the first chamber or the second chamber. A first valve can be closed by a prong of the valve body in the first position such that unfiltered fluid enters an inlet of the oil separator, waste byproducts collect in a reservoir defined by the container, and filtered fluid is output from an outlet. The valve body can move from first to second positions with an accumulation of byproducts in the reservoir. In the second position unfiltered fluid may pass from the inlet to the outlet.
