.... and more popular and important in computer graphics research and applications [Deb97a] Debevec proposed a simple method to compose high dynamic range images from a series of common photographs with different exposures [Deb97a] High dynamic range images are a natural outcome of various renders [War97a]. However, the high dynamic range image also brings challenges for display, because the existing presentation devices, including CRT monitors, printers, liquid crystal display, have low dynamic ranges. A simple linear tone mapping will cause loss of much detail. So, advanced range compression ....
....is to separate the profile and the detail from the signal. Tumblin et al. [Tum99b] developed an LCIS based approach to carry out this separation. In this paper we propose a simpler approach based on level set method. 2. RELATED WORK A lot of work has been done on this topic over the past years [Ash02a, Dur02a, Fat02a, Pat98a, Rei02a, Rah96a, Sch94a, Tum99b, War97a]. For a detailed review, refer to [Dic01a, Rei02a] In this section we will restrict our discussion only to the work of [Tum99a] which is more relevant to our work. Tumblin s LCIS Based on the observation that artists are able to create very realistic painting starting with the profile of the ....

....will ultimately need confirmation with experiment. 8.2.3 Tone mapping Once a high dynamic range image is captured, corrected for FPN and rendered into a standard colour space, a problem remains in terms of display. Standard displays are incapable of rendering more than two decades of illuminance [5]. A solution to this problem does not necessarily require a high dynamic range display although the development of such a display would enhance the sense of virtual reality. Rather, the high dynamic range image must be mapped to the low dynamic range display with a minimal loss of perceptual ....

....the real world image and the display image. If the display luminance falls outside the range of the frame buffer then the frame buffer value is clamped to fit this range. This method is limited to greyscale and by the preservation of brightness at the expense of visibility in high dynamic scenes [18]. It has been noted that as the operator can handle extremes of brightness, some images tend to appear too dark but this may work in its favour if the analysis of extreme lighting conditions is required [19] Ward s model [45] dealt with the preservation of perceived contrast rather than ....

To render the image shown in Figure 3, we compressed the data using a logarithmic transformation. More sophisticated algorithms have been explored, and more work on this topic is needed [94 96]. All electronic image sensors include temporary memory to support external transfer of image data from the pixels array. In CCD image sensors, the temporary memory is in the form of analog shift registers (vertical and horizontal CCDs) In CMOS image sensors with analog pixels [97, 98] the ....

....The monitor was calibrated to ensure linearity before every session of the experiment. Third, we applied synthetic glare to the rendered images in order to mimic the optical effects of viewing high luminances with the human eye. This was done according to specifications derived by Ward et al. [12] from empirical measurements of the optical properties of the eye. This process simulates the glare that would be experienced had the brightest points in the images really been shown at their correct luminances. The process has little effect except for bright point sources. Procedure. Each ....
