Abstract
   It is an attempt to construct an electric version of anatomical/functional atlas of Hypothalamus region from the high resolution pictures of cadaver dissection provided by the Visible Human Project of NIH.
  Visible Human Project supplies dissection picture sets of one male and one female. The picture of female is in resolution isotropic 0.33 mm/pixel, which is twice to more than ten times better than CT and MRI. The authors constructed a Sagittal slice set of Hypothalamus region from the original Axial slice set. The picture was stored in HyperCAS format, developed by the authors. HyperCAS was extended so that the coordinate value of each data set was able to reference on the other set.

Fig. 1; Reduction of the variance of luminance in the horizontal lines. lij is the luminance at pixel (i,j). It is, in basic, smoothing by the binomial kernel. After the smoothing, RGB values are updated so that the hue and saturation values are preserved. We set N=10, M = 2, and a=0.
