摘要： Systems in accordance with embodiments of the invention can perform parallax detection and correction in images captured using array cameras. Due to the different viewpoints of the cameras, parallax results in variations in the position of objects within the captured images of the scene. Methods in accordance with embodiments of the invention provide an accurate account of the pixel disparity due to parallax between the different cameras in the array, so that appropriate scene-dependent geometric shifts can be applied to the pixels of the captured images when performing super-resolution processing. In several embodiments, detecting parallax involves using competing subsets of images to estimate the depth of a pixel location in an image from a reference viewpoint. In a number of embodiments, generating depth estimates considers the similarity of pixels in multiple spectral channels. In certain embodiments, generating depth estimates involves generating a confidence map indicating the reliability of depth estimates.
摘要翻译：根据本发明的实施例的系统可以在使用阵列相机拍摄的图像中执行视差检测和校正。由于摄像机的不同观点，视差导致场景拍摄图像内物体位置的变化。根据本发明的实施例的方法提供了由于阵列中的不同相机之间的视差引起的像素差异的准确描述，使得当执行超分辨率时，适当的与场景相关的几何移位可应用于所捕获图像的像素处理。在几个实施例中，检测视差涉及使用图像的竞争子集从参考视点估计图像中的像素位置的深度。在多个实施例中，生成深度估计考虑了多个频谱信道中的像素的相似度。在某些实施例中，生成深度估计涉及生成指示深度估计的可靠性的置信图。
