为解决目前采用形变技术的图像适应方法难以处理多焦点图像的问题，提出一种基于鱼眼变换技术的图像适应方法。这种方法既能够突出显示图像中需要关注的区域，又能够保留图像的背景信息，而且能够解决多焦点图像的适应问题。对于具有多焦点的图像，首先计算出各焦点之间的距离，通过设定合适的阈值，选择采用正交鱼眼变换或将图像分割后使用全域鱼眼变换，以解决可能出现的多焦点冲突问题。实现效果和用户主观评价结果表明，提出的方法对于解决多焦点图像适应问题是一种可行的方案。

In order to solve the multi-focus problem, which is a difficult issue for image retargeting based on existing warping methods, a fisheye transformation method is proposed in this paper. The method emphasizes areas of interest while keeping the background information and it can solve the multi-focus problem in image retargeting. For a multi-focus image, the distances among focuses are calculated first, and then the transformation method is selected. According to a predetermined threshold, the selected transformation method can be full-area fisheye transformation after splitting the image or orthogonal fisheye transformation. The visual effect of target images and users’ subjective satisfaction showed that our method is a viable solution for multi-focus image retargeting.
