1. A video processing apparatus configured to process a stream of video surveillance data, wherein the video surveillance data includes metadata associated with video data, the metadata describing at least one object in the video data, comprising:
at least one memory storing instructions; and
at least one processor executing the instructions causing the video processing apparatus to:
apply an image assessment algorithm to generate a reliability score for the metadata, and associating the reliability score with the metadata, wherein the image assessment algorithm generates the reliability score based on an assessment of the image quality of the video data to which the metadata relates, to indicate a likelihood that the metadata accurately describes the object; and
apply image enhancement to video data if the reliability score of metadata associated with the video data indicates a low likelihood that the metadata accurately describes the object,
wherein the image assessment algorithm is a non-reference based algorithm.
