1. A stereo matching method, the method comprising:
obtaining a first feature map associated with a first view image and a second feature map associated with a second view image using a neural network model-based feature extractor;
determining respective matching costs between a reference pixel of the first view image and candidate pixels of the second view image using the first feature map and the second feature map; and
determining a pixel corresponding to the reference pixel among the candidate pixels based on the determined matching costs,
wherein the determining of the respective matching costs comprises:
determining an initial matching cost between the reference pixel and a current candidate pixel; and
adjusting the initial matching cost based on matching cost information associated with another reference pixel adjacent to the reference pixel.
