Abstract
A method includes obtaining input image frames, including at least two captured using different capture conditions, separating color channels of each image frame, and generating at least one bad pixel map for each color channel of each image frame. Each bad pixel map is generated by identifying one or more outliers in pixel values in the color channel based on an intensity distribution of pixel values in an operation window within the color channel. The operation window has a window size based on the capture condition and/or local image content in the corresponding image frame. The method also includes combining the bad pixel maps and performing a morphological operation to refine the combined bad pixel map and using one or more coordinates of one or more bad pixels in the refined bad pixel map to update one or more pixel values of at least one image frame.
