Automatic tone scale adjustment using image activity measures |
| abstract |
A method of automatic tone scale adjustment for digital radiographic images comprising the steps of:providing an input digital radiographic image;estimating the image noise as a function of code value of the image;determining the range of code values in the input image;determining which way the input image should be processed;determining a bounding box which contains the region of interest of the input image;computing the image activity histogram of the input image;determining four points from the image activity histogram;constructing the tone-scale curve for the input image; andmapping the input image through the tone-scale curve to produce an output image with good tone scale. |
