根据典型的视觉重建方法，视觉系统必须首先在内部重建世界，然后从结果表示中提取手头任务所需的任何特征。计算视觉和视觉神经科学的最新发展表明，从空间辨别到物体识别等任务所需的许多特征都可以直接从图像中提取，就像吉布森的直接感知假设一样。在吉布森的立场和马尔的立场之间正在出现的综合中，再现（不一定是重建）发挥着核心作用。这种新的综合似乎在有目的的视觉信条的极端版本（用布鲁克斯的话说，是没有表征的视觉）和无目的的重建的统治范式之间构成了合理的妥协。
According to the paradigmatic reconstructionist approach to vision, a visual system must first reconstruct the world internally, then extract from the resulting representation whatever features are necessary for the task at hand. Recent developments in computational vision and visual neuroscience show that many of the features needed for tasks ranging from spatial discrimination to object recognition can be extracted from the image directly, much as in Gibson's hypothesis of direct perception. In the emerging synthesis between Gibson's position and that of Marr, representation, and not necessarily reconstruction, plays a central role. This new synthesis seems to constitute a reasonable compromise between the extreme version of the purposive vision credo, which, paraphrasing Brooks, is vision without representation, and the reigning paradigm of reconstruction without purpose.
