Abstract
A method for producing a labeled image is provided. The method includes steps of: a labeling server (i) providing an image modifying interface to a user device to generate at least one anonymized image by anonymizing the original image except a specific labeling region among at least one labeling region, or generate at least one cropped image by cropping the labeling region, thus generating at least one transformed image by applying at least one transform function to the anonymized image or the cropped image, (ii) acquiring an obfuscated image by obfuscating the original image, (iii) acquiring at least one partial labeled image by allowing labelers to label the transformed image, and (iv) inversely applying the transform function received from the user device to the partial labeled image, thus generating at least one piece of adjusted partial labeling information and combining thereof with the obfuscated image to generate the labeled image.
