1. A system, comprising: a memory; a first processor that is coupled to the memory, wherein the first processor is to perform a first linear interpolation between a first mapping matrix of a previous frame and a second mapping matrix of a subsequent frame to obtain a third mapping matrix of a third frame to a model, in response to determining that the third frame may have insufficient key points to obtain the third mapping matrix, wherein the third frame is located between the previous frame and the subsequent frame.
