color points

[yangqun-os]

There is no color points in the original night image. After reading it into the project, it is found that there are color points. Have you ever been in this situation?

Sorry, I don't understand. What do you mean by "color points"?

[yangqun-os]

Thank you for your response. I've run through the engineering, and the images show color noise. The enlarged image is shown in fig. You can see the color noise, but the original image is normal。

The noise level depends on the settings in step 4) Accumulate, to a large extend especially on the kDetail and kDenoise values which are the sigmas for areas detected as being not noisy or noisy (sigma = number of pixels averaged surrounding a given pixel). With a large value for kDetail and kDenoise you will get smoother images with less noise.

Thank you for your explanation. When I read the image into the interface, I found that there was noise in the interface display without later processing.In addition, can we give some raw graphs like this.
