METHOD AND APPARATUS FOR IMAGE PROCESSING
First Claim
Patent Images
1. A method of processing an image, the image processing method comprising:
- receiving an object transmission photographed image as an input image;
obtaining a threshold which is applied to remove noise in the input image, based on at least one image information from among information related to pixel intensity of the input image and an edge map; and
removing the noise from the input image by using the threshold.

Abstract
An image processing method and apparatus includes receiving a transmission image as an input image, obtaining a threshold which is applied to noise removal, based on at least one image information from among information related to a pixel intensity of the input image and an edge map, and removes noise in the input image by using the threshold.

23. An image processing apparatus for removing noise from an image, the image processing apparatus comprising:
-
an image receiver configured to receive a transmission image as an input image; and an image processor configured to obtain a threshold which is applied to remove noise, based on at least one image information from among information related to a pixel intensity of the input image and an edge map, and removing noise in the input image by using the threshold, wherein the image processor reduces the threshold, which is applied to noise removal in an edge area of the input image, based on the edge map, and an edge enhancer configured to adjust the pixel intensity at the edge in the input image (Sin). - View Dependent Claims (24, 25, 26, 27)
