Abstract: Systems and methods for depth estimation are provided. One aspect of the systems and methods includes obtaining an image. Another aspect of the systems and methods includes generating a depth map of the image using a monocular depth estimation (MDE) network, where the MDE network is trained using training data including edge data generated by a depth edge estimation (DEE) network.

Abstract: There is provided a novel adjustable clasp for suspending a plant, integrally molded of a semi-rigid polymer material and comprising a pair of arcuate arms hinged together by means of an integral hinge section of reduced thickness which tends to bias apart said arms to an open position of the clasp, which can be closed manually to encircle a portion of the plant, the arms being secured in the closed position by interengaging locking means provided at or adjacent the free ends of the arms, e.g. an integral buckle at the end of one arm capable of irreversibly engaging a plurality of integral retaining teeth provided on the outside of the other arm.
