ImageFocusCombine

ImageFocusCombine[{image1,image2,…}]

结合同一场景聚焦不同的图像 imagei 以获得一张聚焦较好的图像.

更多信息和选项

  • ImageFocusCombine 即为景深（DOF）合成，或 Z 通道合成. 其典型应用为结合同一场景的多张不同焦距的图像创建一个更高景深的图像.
  • ImageFocusCombine 假设所有的 imagei 都是对齐的.
  • ImageFocusCombine 采用 PerformanceGoal 选项. 可能的设置包括：
  • "Quality"优化最终结果的质量
    "Speed"优化获取结果的速度

范例

打开所有单元 关闭所有单元

基本范例  (1)

结合一个场景的两张聚焦不同的图片：

Wolfram Language code: ImageFocusCombine[{[image], [image]}]

范围  (1)

结合不同焦平面下的图片栈：

Wolfram Language code: stack = {[image], [image], [image], [image]};
Wolfram Language code: ImageFocusCombine[stack]

选项  (2)

PerformanceGoal  (2)

用 PerformanceGoal->"Quality" 强调结果的质量：

Wolfram Language code: ImageFocusCombine[{[image], [image]}, PerformanceGoal -> "Quality"]//AbsoluteTiming

用 PerformanceGoal->"Speed" 强调运算速度：

Wolfram Language code: ImageFocusCombine[{[image], [image]}, PerformanceGoal -> "Speed"]//AbsoluteTiming

应用  (1)

在焦点在三个不同区域的三张图像上反转移轴效果：

Wolfram Language code: ImageFocusCombine[{[image], [image], [image]}]

与开始时的图像比较：

属性和关系  (1)

焦点所在的区域由图像中的高频位置定义：

Wolfram Language code: image = [image];

将图像和一张随机的高频图像结合：

Wolfram Language code: random = RandomImage[1, ImageDimensions@image];ImageFocusCombine[{image, random}]

将这个图片和一张随机的低频滤波图像相结合：

Wolfram Language code: ImageFocusCombine[{image, GaussianFilter[random, 4]}]

可能存在的问题  (2)

ImageFocusCombine 不校正错边：

Wolfram Language code: images = {[image], [image], [image], [image]};
Wolfram Language code: ImageFocusCombine[images]

在结合图像前使用 ImageAlign 对齐图像：

Wolfram Language code: alignedimages = ImageAlign[images];
Wolfram Language code: ImageFocusCombine[ImagePad[#, -7]& /@ alignedimages]

有些情况下错边情况太严重则无法自动校正：

Wolfram Language code: images = RemoveAlphaChannel /@ ImageAlign[{[image], [image], [image]}];

这常常会导致鬼影效果：

Wolfram Language code: ImageFocusCombine[images]
Wolfram Language code: ImageDifference@@@{images[[{1, 2}]], images[[{1, 3}]]}

手动移除图像栈中错边最严重的图像来缓和重影问题：

Wolfram Language code: ImageFocusCombine[images[[{1, 2}]]]
