| 摘 要： | 由散焦图像求深度是计算机视觉中一个非常重要的课题。散焦图像中点的模糊程度随物体的深度而变化，因此可以利用散焦图像估计物体的深度信息，该方法不存在立体视觉和运动视觉中对应点的匹配问题，具有很好的应用前景。研究了一种基于散焦图像空间的深度估计算法：将散焦成像描述成热扩散过程，借助形变函数将两幅散焦图像扩张成一个散焦空间，再估计出形变参数，进而恢复物体的深度信息。最后利用实验验证了算法的有效性。

| Abstract: | To find the depth from defocus image is an important subject in computer vision.Since the blur level of a point in defocus image varies according to the depth of the object,thus defocus image can be used to estimate the depth information of an object.The approach proposed in this paper does not have matching problem of corresponding points in stereo vision and motion vision,so it has quite good applicative prospects.An algorithm of depth estimation based on defocus image space is studied.In the algorithm,th... |
