Claim:
A multilevel texture processing method for mapping an image onto a 3D model with a texture mapping, the method comprising the steps of providing the image to the 3D model; converting the image and the texture mapping to a common spatial coordinate system and dividing them into a plurality of polygons; comparing the image with the texture mapping within the spatial coordinate system to extract overlapped polygons; using the pixel intensity of the overlapped polygons to compute a statistics mean for adjusting the pixel intensity of the image accordingly, using a prescribed condition to select the texture of one of the image and the texture mapping as the texture of polygon of the overlapped polygons; smoothing the texture of the polygon, making the pixels inside the polygon continuous; and restoring the polygon and storing the 3D model in memory, wherein the pixel intensity of the image is adjusted by a formula, I′ s ( x i ,y i )= I s ( x i ,y i )−μ s +μ b , μ s representing the averaged pixel intensity of the overlapped polygons on the 3D model. μ b representing the averaged pixel intensity of the overlapped polygons of the input image, I s (X i ,Y i ) representing the pixel intensity of each point on time 3D model, and I′ s (X i ,Y i ) representing the adjusted pixel intensity of each point on the 3D model.
