1. A method for estimating one or more physical properties associated with an object, the method comprising:
generating a three-dimensional (3D) reconstruction of a real-world environment based on an input media from a capturing device;
estimating a current set of physical parameters associated with the object using a physics-based prediction model and a real-world visual content indicating a recorded media while the object is manipulated in the real-world environment;
generating a simulation variant corresponding to the manipulation of the object based on the 3D reconstruction and the current set of physical parameters;
computing a cost function based on comparing the simulation variant and the real-world visual content, wherein the cost function indicates dissimilarity between the simulation variant and the real-world visual content; and
estimating the one or more physical properties associated with the object based on optimizing the current set of physical parameters with the cost function such that a similarity between the simulation variant and the real-world visual content increases.
