Method of processing radiograph and apparatus for processing radiograph using the method in which hough transform and radon transform performed on image

摘要

Provided are an apparatus and a method for processing a radiograph which is capable of precisely detecting a region of interest. The apparatus includes: an inputter that outputs an input image obtained by irradiating radioactive rays; and a line detector that performs a Hough transform on the input image, senses at least one edge line based on the Hough-transformed input image, performs a Radon transform in a region in which the at least one edge line is sensed, and obtains an edge line of the at least one edge line as a first collimation line one based on a result of the Radon transform.

1. An apparatus for processing a radiograph, the apparatus comprising:
an inputter which outputs an image obtained by irradiating radioactive rays; and a line detector which performs a Hough transform on the image output from the inputter, senses at least one first edge line based on the Hough-transformed input image, performs a first Radon transform on a region in which the at least one first edge line is sensed, and obtains, as a first collimation line, an edge line from among the at least first one edge line based on a result of the first Radon transform.
