A “Joint Bilateral Upsampler” uses a high-resolution input signal to guide the interpolation of a low-resolution solution set (derived from a downsampled version of the input signal) from low-to high-resolution. The resulting high-resolution solution set is then saved or applied to the original input signal to produce a high-resolution output signal. The high-resolution solution set is close to what would be produced directly from the input signal without downsampling. However, since the high-resolution solution set is constructed in part from a downsampled version of the input signal, it is computed using significantly less computational overhead and memory than a solution set computed directly from a high-resolution signal. Consequently, the Joint Bilateral Upsampler is advantageous for use in near real-time operations, in applications where user wait times are important, and in systems where computational costs and available memory are limited.

The invention claimed is: 1. A method for upsampling a solution set, comprising using a computing device to:perform steps for:receiving a high-resolution input signal having a first resolution;receiving a low-resolution solution set computed from a downsampled version of the high-resolution signal, said low-resolution solution set having a second resolution lower than the first resolution;performing a joint bilateral upsampling using the low-resolution solution set and the high-resolution signal to generate a high-resolution solution set having a resolution equivalent to the first resolution; andstoring the high resolution solution set for later use by a user.
