Joint bilateral upsampling

A physical computer-readable storage device having computer executable instructions stored therein for generating a high-resolution output signal from a high-resolution input signal, said computer executable instructions comprising:

• receiving a high-resolution input signal;
• downsampling the input signal to produce a downsampled signal;
• processing the downsampled signal to generate a low-resolution signal solution;
• performing a joint bilateral filtering of the low-resolution signal solution and the high-resolution input signal to generate a high-resolution signal solution;
• and
• applying the high-resolution signal solution to the high-resolution input signal to generate a high resolution output signal.

A camera for processing images in near real-time, comprising using a computing device embedded within the camera for:

• capturing a high-resolution input image;
• downsampling the input image;
• processing the downsampled input image to generate a low-resolution image solution;
• performing a joint bilateral filtering of the low-resolution image solution relative to the high-resolution input image to generate a high-resolution image solution;
• and
• applying the high-resolution image solution to the high-resolution input image to generate a high-resolution output image.
