Stereo depth estimation utilizing asymmetric downsampling in different directions

A method for providing a stereo image, the method comprising:

• capturing one or more images, wherein each of the images includes one or more patches, each patch including plurality of pixels;
• down-sampling in a first direction on a first set of pixels in a first patch of a first image to generate a first down-sample;
• and
• down-sampling in a second direction on a second set of pixels in a second patch of a second image to generate a second down-sample, wherein, the second down-sample includes a greater number of pixels.

A non-transitory computer-readable data storage medium having stored thereon instructions that, when executed, cause one or more processors to:

• capture one or more images, wherein each of the images includes one or more patches, each patch including plurality of pixels;
• down-sample in a first direction on a first set of pixels in a first patch of a first image to generate a first down-sample;
• and
• down-sample in a second direction on a second set of pixels in a second patch of a second image to generate a second down-sample, wherein, the second down-sample includes a greater number of pixels.
