Abstract:
A computer-implemented process for reconstructing a single, combined texture from multiple input textures each of which represents the same portion of a scene and each of which was taken from images of the scene captured from different perspectives, the process comprising using a computer to perform the following process actions:resampling the multiple textures, wherein each input texture is a digitized texture defined by a discrete signal comprising a value of a prescribed texture attribute at each prescribed point of the texture, and wherein resampling the multiple textures, comprises, for each input texture,: reconstructing a continuous signal from the digitized input texture, warping the reconstructed continuous signal to a prescribed location, prefiltering the warped signal to remove any frequencies in the warped signal that are higher than a prescribed maximum frequency, and sampling the warped and filtered signal to produce a discrete output signal that represents the resampled texture; computing a weight matrix for each input texture from its corresponding resampled texture which comprises spatially-variant weights; and blending the input textures using the weight matrices to produce said single combined texture.
