Method of processing optical coherence tomographic image and apparatus for performing the method
First Claim
1. A method of processing an optical coherence tomographic image, the method y comprising:
- obtaining an optical coherence tomographic image by irradiating light to an object;
generating a color space map based on the obtained optical coherence tomographic image;
normalizing data of the obtained optical coherence tomographic image;
realigning the normalized data of the optical coherence tomographic image;
performing tone mapping on the realigned data of the optical coherence tomographic image; and
generating a color image by mapping the data of the optical coherence tomographic image on which the tone mapping is performed, by using the generated color space map,wherein properties of the color space map comprise a hue having a linear characteristic, while a brightness and a saturation have a non-linear characteristic, andwherein mapping values of hue corresponding to gray level intensity values are set to have a constant gradient.
