A plurality of input images are received from a sensor (e.g., a camera), wherein each input image includes a plurality of pixels. Utilizing an image-to-image machine-learning model, each pixel is assigned a new pixel color.

One or more parameters of the image-to-image machine-learning model and the mixer model are updated based on the loss function. The process repeats, with each iteration updating the parameters of the image-to-image machine-learning model and the mixer model, until convergence, resulting in trained models.

Abstract: An oval cover member is formed of high density polyethylene and sized to cover a pocket in which a lift member is secured to a pre-cast concrete structural member. The cover member can be secured to the lift member by a cable tie threaded through the opening of a first protrusion, back through a smaller opening in a second protrusion and pulled to draw the cover member tightly against the concrete structural member. The opposing protrusions form a valley therebetween for the positioning of the lift member. The size of the smaller opening in the second protrusion is too small for the passage of the head of the cable tie, enabling the cover member to be tightly secured to the lift member. A peripheral channel in the cover member can receive a gasket or adhesive that can seal the cover member against the surface of the concrete structural member.

A method is provided for generating a secondary seal between the frame and cover by applying an amount of a viscous compound to a circumferential surface of the frame or cover, wherein the secondary seal is formed when the cover compresses the compound when the cover is received within the frame.
