Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
50 words
A method for generating a textured range image, comprising: acquiring a first image of a scene illuminated with ambient light; acquiring a second image of the scene illuminated with direct light; combining the first and second images; and generating a textured range image from the combined first and second images.
Claim 2
Independent Claim
50 words
A method for generating a textured range image, comprising: acquiring a first image of a scene illuminated with ambient light; acquiring a second image of the scene illuminated with direct light; combining the first and second images; and generating a textured range image from the combined first and second images.
Claim 3
Dependent Claim
24 words
The method of claim 1 wherein the combining further comprises: dividing pixel values of the first image by pixel values of the second image.
Claim 4
Dependent Claim
19 words
The method of claim 1 wherein the first and second images are acquired from substantially identical points of view.
Claim 5
Dependent Claim
18 words
The method of claim 1 further comprising: enhancing the textured range image with a 2D image editing system.
Claim 6
Dependent Claim
16 words
The method of claim 4 wherein the textured range image is combined with other 2D images.
Claim 7
Dependent Claim
16 words
The method of claim 4 wherein the textured range image is combined with 2D gradient filters.
Claim 8
Dependent Claim
16 words
The method of claim 4 wherein the textured range image is enhanced with 2D image brushes.
Claim 9
Dependent Claim
12 words
The method of claim 7 wherein the 2D image brushes are gradient-based.
Claim 10
Dependent Claim
12 words
The method of claim 7 wherein the 2D image brushes are procedural-based.
Claim 11
Dependent Claim
17 words
The method of claim 7 wherein the 2D image brushes are derived from the textured range image.
Claim 12
Dependent Claim
49 words
The method of claim 1 further comprising: acquiring a sequence of pairs of first and second images with the ambient and direct light; combining the pairs of first and second images of the sequence; and generating a 3D textured video from the combined pairs of first and second images.
