Abstract
A method for de-identifying a privacy-related region within an image, including steps of: (a) inputting an input image into a segmentation network to apply a segmentation operation to the input image and generate at least part of (i) each of region probabilities of each of the pixels being estimated as the privacy-related region and (ii) each of region sizes assigned to each of the pixels of the input image; and (b) (i) calculating each of standard deviations for each of the pixels of the input image by using at least part of each of the region probabilities and each of the region sizes, thereby generating each of region standard deviations and (ii) applying a de-identifying operation to each of the pixels of the input image by using each of the region standard deviations, to thereby de-identify the privacy-related region within the input image.
