    摘要: In a photography method, a determination is made that a set of captured images includes one or more encoded captured images having a partial shading encodement. The encodement has a predetermined edge pattern and is disposed within a predetermined subarea of an image. An encoded captured image is digitized to provide a digital image having a plurality of pixels. A plurality of pixel templates of an edge pattern and the pixels in the subarea of the digital image are convolved to provide a plurality of template position metrics. Each pixel template has the same shape. Each pixel template is differently located in said subarea. The highest of the template position metrics and a predetermined threshold template position metric value of the edge pattern are compared. The digital image is digitally modified when said highest template position metric matches the threshold template position metric value.

    摘要: A method for compensation at least one digital image for light falloff. The digital image may be generated for example from a conventional image frame on a film roll. A plurality of pixel values is provided for each of at least one digital image. A light falloff compensation function is applied and according to that a light falloff correction parameter is determined. Both the light falloff compensation function and the light falloff correction parameter are used to generate an individual compensation value for each pixel element. The compensation value is applied to each pixel element. The method is also able to differentiate and correct the images according to light falloff generated by pure lens falloff or a light falloff generated by the lens and the flash falloff.

    摘要: A method and a system are disclosed for labeling an anatomical point associated with a lesion in an organ such as a lung. The method includes: a segmentation of a vessel tree anatomical structure starting from an autonomously determined initial image point; labeling the vessel segments of the vessel tree segmentation with segment labels based on a priori anatomical knowledge, thereby creating an individualized anatomical model; receiving a user-specified image point having a location from a user and locating a nearby vessel structure; tracking along the vessel structure in a direction towards a root of a parent vessel tree until a prior labeled vessel segment is encountered in the anatomical model, and assigning the label of the encountered prior labeled vessel segment from the anatomical model as an anatomical location label of the user-specified image point.

    摘要: A method for processing a source digital image wherein the source digital image is comprised of a plurality of pixels. A spatial filter is applied to the source digital image to produce an enhanced digital image. An inverse spatial filter is applied to the enhanced digital image to produce an estimated digital image. A difference digital image is then produced from the estimated digital image and the source digital image, wherein the difference digital image is representative of a difference between the source digital image and the estimated digital image. The difference digital image and the enhanced digital image can be transmitted from a first device to a second device remote. At the second device, a reconstructed digital image can be generated from the difference digital image and the enhanced digital image, wherein the reconstructed digital image is substantially equivalent to the source digital image.
