Orientation detection for chest radiographic images |
摘要 |
A method for identifying the orientation of a radiographic image of a patient generates a reduced-scale image having a smaller number of pixel elements than the original radiographic image and generates a reduced bit-depth image from the reduced-scale image. The method determines whether the image has portrait or landscape orientation by sectioning either the reduced-scale image or the reduced bit-depth image into at least two sections and calculating at least one value related to relative symmetry for each of the at least two sections. |
