METHOD AND APPARATUS FOR DETECTING EDGE OF IMAGE AND COMPUTER READABLE MEDIUM PROCESSING METHOD

摘要

The present invention provides a method and apparatus for detecting a noise distribution of an image close to a true distribution, and detecting an edge of the image precisely and quickly based on the detected noise distribution without performing a smoothing process for the image, and a computer readable medium processing the method. The method of detecting an edge of an image includes the steps of: detecting a noise distribution of an object image; and detecting an edge of the image based on the detected noise distribution.
