Abstract
Digital signal representations of sub-images are obtained by applying an optimization process wherein a sum is minimized, the sum having a first term representing a measure of the consistency of the sum of a digital representations of sub-images with said radiographic image and wherein the second term is a sum of cost functions each describing the type of one of said sub-images.
Claims18
A method comprising:
- decomposing a digital signal representation of an image into a sum of sub-images of different image types selected from the group consisting of a radiographic image, a collimation area image, a bone image, a soft tissue image, a noise image, a scatter image, a heel effect representing image, and an implant image, and
- minimizing a first term representing a measure of the consistency of the sum of the sub-images with said image and a second term representing a sum of cost functions of the different sub images, each describing the likeliness of the image being a member of the type of the sub-images, wherein different image processing is applied to said sub-images.
A computer-readable medium storing processor-executable instructions that, when executed by a processor, configure the processor for:
- decomposing a digital signal representation of an image into a sum of sub-images of different image types selected from the group consisting of a radiographic image, a collimation area image, a bone image, a soft tissue image, a noise image, a scatter image, a heel effect representing image, and an implant image, and
- minimizing a first term representing a measure of the consistency of the sum of the sub-images with said image and a second term representing a sum of cost functions of the different sub images, each describing the likeliness of the image being a member of the type of the sub-images, wherein different image processing is applied to said sub-images.
