Methods and systems for combining a plurality of radiographic images
View Patent ↗Methods and systems for combining a plurality of radiographic images. Software can be used to provide various stitching and blending methods to join first and second images into a composite, larger image.
1. A method of blending at least a first and second radiographic image in an overlap section of a stitched image using a computer system, the method comprising:
computing via a processor a pixel intensity of the first image and second image in the overlap section of the stitched image; and
displaying by a graphical user interface a smooth transition in the overlap section between the first and second image from 0% to 100% of the pixel intensity of the second image.
2. The method of claim 1 wherein displaying the smooth transition comprises:
displaying 100% of the pixel intensity first image at a first end of the overlap section;
blending 50% of the pixel intensity of the first and second images at a half point; and
displaying 100% of the pixel intensity of the second image at a second end of the overlap section;
wherein the distribution of the smooth transition of the pixel intensity between the first end, half point, and second end varies with linear weighting.
3. The method of claim 1 wherein displaying the smooth transition comprises:
displaying 100% of the pixel intensity first image at a first end of the overlap section;
blending 50% of the pixel intensity of the first and second images at a half point; and
displaying 100% of the pixel intensity of the second image at a second end of the overlap section;
wherein the distribution of the smooth transition of the pixel intensity between the first end, second end, and half point varies with non-linear weighting.
4. A method of blending at least a first and second stitched image using a computer system, wherein the first image and second image comprises pixels, wherein the stitched image defines an overlap section in which portions of the pixel in the first image overlap with pixels in the second image, the method comprising:
computing via a processor a pixel intensity for each of the pixels from the first and second image in the overlap section; and
displaying by a graphical user interface a largest computed pixel intensity of the overlapping pixels from the first and second images.
5. A method of blending at least a first and second stitched image using a computer system, wherein the first image and second image comprises pixels, wherein the stitched image defines an overlap section in which portions of the pixel in the first image overlap with pixels in the second image, the method comprising:
computing via a processor a pixel intensity for each of the pixels from the first and second image in the overlap section; and
displaying by a graphical user interface a smallest computed pixel intensity of the overlapping pixels from the first and second images.
6. A method of stitching a plurality of images using a computer system, the method comprising:
providing a first image and a second image to a processor;
allowing a user to choose via a user interface one of at least two types of markers to align the first and second images;
marking the first image and second image with a chosen marker; and
aligning the markers to stitch the first and second images together.
7. The method of claim 6 wherein allowing comprises letting the user choose from at least two of a single point marker, two point markers, a line marker, and a point and line marker.
8. The method of claim 6 wherein marking comprises marking the first image and second image with a point marker, and wherein aligning comprises performing at least one of a translation (with no rotation) of one of the images to align the markers on the first image and second image.
9. The method of claim 6 wherein marking comprises marking the first image and second image with two point markers, and wherein aligning comprises performing at least one of a translation and rotation of one of the images to align the two markers on the first image with the two markers on the second image.
10. The method of claim 6 wherein marking comprises marking the first image and second image with a point marker and a line marker, and wherein aligning comprises performing at least one of a translation and a rotation of one of the images to match the point markers on the first image and second image and to make the line markers parallel.
11. The method of claim 6 wherein marking comprises marking the first image and second image with a line marker, and wherein aligning comprises performing at least one of a translation and rotation of one of the images to match one end of the line marker on the first image with an end of the line marker on the second image and to align the images such that the lines are parallel.
12. The method of claim 6 comprising blending the images in an overlap section of the stitched image.
