Presentation and manipulation of high depth images in low depth image display systems

摘要

High depth grayscale images, (e.g. <8 bits per pixel) are losslessly cross channel encoded to multi-channel image formats for transformation and display by display devices not capable of displaying high depth grayscale. DICOM and other images may be encoded and provided to web browser based client image viewers that leverage native code for handling multi-channel images. Transformations are applied to reconstitute the high depth grayscale images.

主权项

1. A method for encoding first image data, the first image data comprising at least one first image data channel of a first bit depth, the method comprising:
mapping the first image data to second image data at least partly by losslessly mapping the at least one first image data channel to at least two second image data channels of the second image data, the at least two second image data channels of a second bit depth displayable by a display system; and providing the second image data for display by the display system.
