Abstract
A method includes obtaining multiple input image frames and generating bad pixel maps associated with different ones of the input image frames. Each bad pixel map is generated using first and second adaptive thresholds that are based on statistical properties of image data contained in a specified operation window within the associated input image frame. The method also includes generating at least one refined bad pixel map using the bad pixel maps associated with two or more of the input image frames. The method further includes using one or more coordinates of one or more bad pixels identified in the at least one refined bad pixel map to update one or more pixel values of at least one of the input image frames.
