10. Code

We used C++ as our main programming language, although the algorithm should work fine in multiple languages. Since OpenCV supports C++,...

9. Analyzing

The result looks very good, there are some variables to adjust for each specific picture, but it is possible to set some default values,...

8. Filling Colors by Sections

Now we've got different version of the image that has been colored, but it is not enough for a science-fiction style image. Most of them...

7. Generating Color Picker

One thing about the color from the reference color picker that we can tell, is that they usually start from around 0 and ends with around...

6. Analyzing Color Picker

Before, we are using a reference image to generate a color picker. The result is not bad, but the problem is we are relying too much on...

5. Sigmoid function

For the ratio between the color picker and HM image, we would like to pick a curve that makes sense for the science-fiction style image....

4. Generating Color Picker

Now that we got the distribution of light from the previous chapter, we would like to see if we can get fill the color, instead of using...

3.5 More Examples after histogram matching

As we explored in the previous two chapters, we can use histogram matching to simulate the light effect of science-fiction effect, and...

3. HSV color scheme

Last chapter we discussed about how to do the histogram matching and did a lot of examples using different reference images. However, all...

2. Histogram Matching

Last chapter we discovered that we cannot make sure the shape of the science fiction style image's histogram is U-shape, but we can see...

1. Image Histogram Analysis

In order to generate a science-fiction style image, we would like to take a look at the idea of this kind of image. One of the way to...
