本文介绍了如何根据一个特定调整大量图像的颜色?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有大量的照片，我想将它们带到相同的水平"-相同的颜色/亮度/对比度等.为此，我有一个带有黑色和黑色的初始/指南.白色颜色检查器(基本上是带有颜色的方块)，我添加到所有其他照片中.
这是初始/指南
这是我制作的脚本.
请注意，我使用的是您的 png 文件，因此如果您的文件大小不同，您可能需要调整颜色采样器的坐标.

This is the initial / guide https://imgur.com/a/Jlozy1e and these are some of the photos https://imgur.com/JUsKMt2 , https://imgur.com/PvqsleR , https://imgur.com/tcMROU9
As I see it the area with the little square colors (color control squares) must be the same color (hex value) in all photos in order for them to be at the same level -so I can get meaningful data from the strip below.
Is there a way to do with an automated / batch way in photoshop or some other tool?
EDIT: Note that there might be darker / lighter areas than those in the control squares which i want to preserve them (just get lighter/darker accordingly but not completely replace them with a threshold color)
解决方案
I don't know if this is possible with any advanced tool but here's my take in Photoshop. The idea is quite simple — use a gradient map to remap target colors to source values (hence this won't work on 32bit tiffs):
- sample source colors from an active document (source document);
- ask for a path with other documents to open, start to open them one by one;
- sample target colors and get their position for a gradient map
- use source colors and target positions to create a gradient map
Here's the result I got: left row are original documents with a piece of the source squares on top of them for a reference, right row are result documents with the gradient map applied and the same slice from the source doc on top (barely visible):
And here's the script I made.
Note that I was using your png files so if your files are different size you might need to adjust coordinates for color samplers.
var sampler, sampledColors, sourceCoords, targetCoords;
// defining coordinates to sample 6 colors from the active source-document
sourceCoords = [
[55, 318],
[190, 318],
[310, 318],
[420, 318],
[560, 318],
[690, 318],
];
// defining coordinates to sample target colors from target documents
targetCoords = [
[78, 120],
[206, 120],
[328, 120],
[453, 120],
[577, 120],
[709, 120],
]

{
return app.activeDocument.colorSamplers.add(coord);

readSample: function(sample)

return sample.color;
},
// gets a collection of Color Samplers
getSamplers: function()
{
return app.activeDocument.colorSamplers;
},
// deletes a Color Sampler
deleteSample: function(sample)
{
sample.remove();

// RGB > YUV color translation
rgb2yuv: function(rgb)
{
var r = rgb[0] / 255,
g = rgb[1] / 255,
b = rgb[2] / 255;
var y = (r * 0.299) + (g * 0.587) + (b * 0.114);
var u = (r * -0.14713) + (g * -0.28886) + (b * 0.436);
var v = (r * 0.615) + (g * -0.51499) + (b * -0.10001);
return [y, u, v];
},
// Linear transformation
linear: function(X, A, B, C, D, _cut)
{
var _cut = _cut !== undefined ? _cut : false;
var Y = (X - A) / (B - A) * (D - C) + C
if (_cut)
{
if (Y > D) Y = D;
if (Y < C) Y = C;

return Y;
