Silhouette Maps for Improved Texture Magnification

 Slide 19 of 61 [index] [first] [prev] [next]  

We note that lines between the current silhouette point and its four neighbors break up the cell into 4 regions. We shall call these "skewed quadrants."

Our algorithm shades the point using the color of the sample at its respective quadrant. In this case, the corner color in the point's quadrant is yellow so we shall shade the point in yellow.
