LOCALLY OPTIMIZED TRANSFER FUNCTIONS FOR VOLUME VISUALIZATION

摘要

The invention relates to a system (100) for computing an image based on image data for displaying in a display, the image comprising a first image and a second image, the system comprising a first determination unit (110) for determining a first image data within the image data for computing the first image and for determining a second image data within the image data for computing the second image; a second determination unit (120) for determining a first transfer function for computing the first image and for determining a second transfer function for computing the second image; a third determination unit (130) for determining a viewing direction for computing the first image and for computing the second image; a fourth determination unit (140) for determining a first region of the display for displaying the first image and for determining a second region of the display for displaying the second image; and a computation unit (150) for computing the first image and the second image, thereby computing the image. The system (100) is thus capable of improving the quality of the displayed image by optimizing the first transfer function for computing the first image for displaying in the first display region and by optimizing the second transfer function for computing the second image for displaying in the second display region.
